Each question includes the correct answer and a detailed explanation to help you understand the grammar rules tested on the Digital SAT.<\/p>\n\n\n\n

SAT Grammar Practice Questions: Test Your Skills<\/strong><\/h2>\n\n\n\n
Question 1<\/strong><\/th><\/tr><\/thead>
In biology, many initially disordered systems will naturally move toward greater order according to the principle of self-organization, a conceptual framework for pattern _____ biologists believe can be used to explain a range of organic phenomena, from population dynamics to the sociality of bees and ants.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

Which choice completes the text so that it conforms to the conventions of Standard English?<\/strong><\/p>\n\n\n\n

A. formation. Some<\/p>\n\n\n\n

B. formation; some<\/p>\n\n\n\n

C. formation that some<\/p>\n\n\n\n

D. formation, that some<\/p>\n\n\n\n

Answer:<\/strong> C<\/strong><\/p>\n\n\n\n

Skill Tested:<\/strong> Restrictive Relative Clauses<\/p>\n\n\n\n

Explanation:<\/strong><\/p>\n\n\n\n

The noun phrase “a conceptual framework for pattern formation”<\/em> is modified by a restrictive relative clause introduced by “that”<\/em>. The phrase “some biologists believe”<\/em> acts as an embedded parenthetical subject\/verb within the clause (“that [some biologists believe] can be used…”<\/em>). No punctuation should separate the head noun from the restrictive relative pronoun “that”<\/em>.<\/p>\n\n\n\n

Question 2<\/strong><\/th><\/tr><\/thead>
Conceptual artist Joan Jonas’s first work, Wind<\/em> (1968), is a silent film depicting people on a beach struggling to move about in extremely windy conditions. Wind<\/em> has been recognized for bringing the principles of postmodern dance\u2014which demystifies choreography by foregrounding traditional features of movement that ballet and other classical dance forms obscure (such as clumsiness, weightiness, resistance, and _____ to video.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

Which choice completes the text so that it conforms to the conventions of Standard English?<\/strong><\/p>\n\n\n\n

A. gravity),<\/p>\n\n\n\n

B. gravity);<\/p>\n\n\n\n

C. gravity)<\/p>\n\n\n\n

D. gravity)\u2014<\/p>\n\n\n\n

Answer:<\/strong> D<\/strong><\/p>\n\n\n\n

Skill Tested:<\/strong> Parenthetical Phrases and Nested Structures<\/p>\n\n\n\n

Explanation:<\/strong><\/p>\n\n\n\n

The main clause structure is “bringing the principles of postmodern dance … to video.”<\/em> The em dash (\u2014) opens a nonessential parenthetical thought defining postmodern dance. That parenthetical thought contains a parenthetical list enclosed in parentheses (…). To close the primary nonessential element that began with the opening em dash, a closing em dash is required after the parenthesis. Therefore, the parenthesis closes the list (such as clumsiness, weightiness, resistance, and gravity), and the em dash closes the larger parenthetical insert before returning to the main predicate “to video”<\/em>.<\/p>\n\n\n\n

Question 3<\/strong><\/th><\/tr><\/thead>
In a 2022 study, Wang et al. concluded that artifacts excavated from an archaeological site date to between 39,000 and 41,000 years ago. The reliability of the dates that Wang et al. have posited, which were obtained through processes that determined when buried mineral grains surrounding the ocher artifacts were last exposed to sunlight, _____ in part upon the researchers’ exclusion of mineral grains that lacked adequate sun exposure before burial.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

Which choice completes the text so that it conforms to the conventions of Standard English?<\/strong><\/p>\n\n\n\n

A. depending<\/p>\n\n\n\n

B. depend<\/p>\n\n\n\n

C. having depended<\/p>\n\n\n\n

D. depends<\/p>\n\n\n\n

Answer:<\/strong> D<\/strong><\/p>\n\n\n\n

Skill Tested:<\/strong> Subject-Verb Agreement<\/p>\n\n\n\n

Explanation:<\/strong><\/p>\n\n\n\n

Strip away the intervening nonessential clause (“which were obtained through processes…”<\/em>). The subject of the main sentence is the singular noun phrase “The reliability”<\/em>. A finite singular verb is needed to complete the main clause predicate: “The reliability … depends in part upon…”<\/em><\/p>\n\n\n\n

Question 4<\/strong><\/th><\/tr><\/thead>
In 1977, legendary Puerto Rican performer Rita Moreno won an Emmy Award, making her one of the rare talents to earn the highest honors in television, music, film, and stage entertainment\u2014the Emmy, Grammy, Oscar, and Tony _____ the achievement is known as \u201cwinning the EGOT.\u201d<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

Which choice completes the text so that it conforms to the conventions of Standard English?<\/strong><\/p>\n\n\n\n

A. awards, respectively<\/p>\n\n\n\n

B. awards; respectively<\/p>\n\n\n\n

C. awards, respectively\u2014<\/p>\n\n\n\n

D. awards, respectively;<\/p>\n\n\n\n

Answer:<\/strong> D<\/strong><\/p>\n\n\n\n

Skill Tested:<\/strong> Sentence Structure & Punctuation Boundaries<\/p>\n\n\n\n

Explanation:<\/strong><\/p>\n\n\n\n

The first complete independent clause ends after “respectively”<\/em>, with the em dash setting off an appositive list (“the Emmy, Grammy, Oscar, and Tony awards, respectively”<\/em>). A second complete independent clause begins with “the achievement is known as…”<\/em>. To link two independent clauses without a coordinating conjunction, use a semicolon (D<\/strong>).<\/p>\n\n\n\n

Question 5<\/strong><\/th><\/tr><\/thead>
Polymers used in industrial applications are weakened by environmental stress, mechanical fatigue, and unexpected damage. However, new types of polymers have been engineered to repair ______ aided by embedded microcapsules, such materials begin to self-heal.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

Which choice completes the text so that it conforms to the conventions of Standard English?<\/strong><\/p>\n\n\n\n

A. themselves \u2014 upon fracture \u2014<\/p>\n\n\n\n

B. themselves. Upon fracture,<\/p>\n\n\n\n

C. themselves upon fracture,<\/p>\n\n\n\n

D. themselves, upon fracture,<\/p>\n\n\n\n

Answer:<\/strong> B<\/strong><\/p>\n\n\n\n

Skill Tested:<\/strong> Linking Independent Clauses<\/p>\n\n\n\n

Explanation:<\/strong><\/p>\n\n\n\n

The text consists of two independent clauses:<\/p>\n\n\n\n

    \n
  1. “However, new types of polymers have been engineered to repair themselves.”<\/em><\/li>\n\n\n\n
  2. “Upon fracture, aided by embedded microcapsules, such materials begin to self-heal.”<\/em><\/li>\n<\/ol>\n\n\n\n

    Joining these two independent clauses requires a terminal punctuation mark (a period) or a semicolon. Option B<\/strong> correctly separates the two clauses with a period and attaches the introductory prepositional phrase “Upon fracture”<\/em> to the second sentence.<\/p>\n\n\n\n

    Question 6<\/strong><\/th><\/tr><\/thead>
    Social media platforms have made the collection of qualitative human behavioral data easier than ever. To collect such data by means of social media does raise a serious ethical _________ terms of service stipulate that platforms can analyze users’ accounts and posts, according to sociologist Jose van Dijck, users are not informed when their data are included in behavioral studies.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

    Which choice completes the text so that it conforms to the conventions of Standard English?<\/strong><\/p>\n\n\n\n

    A. concern, though;<\/p>\n\n\n\n

    B. concern: though<\/p>\n\n\n\n

    C. concern, though<\/p>\n\n\n\n

    D. concern, though:<\/p>\n\n\n\n

    Answer:<\/strong> B<\/strong><\/p>\n\n\n\n

    Skill Tested:<\/strong> Colons & Subordinating Conjunctions<\/p>\n\n\n\n

    Explanation:<\/strong><\/p>\n\n\n\n

    The first clause introduces a general statement (“does raise a serious ethical concern”<\/em>). A colon is appropriate here to introduce an explanation or elaboration of that concern. The subordinating conjunction “though”<\/em> introduces the dependent clause “though terms of service stipulate…”<\/em>, which contrasts with the main clause “users are not informed…”<\/em>. Option B<\/strong> correctly places the colon after “concern”<\/em> to introduce the detailed explanation.<\/p>\n\n\n\n

    Question 7<\/strong><\/th><\/tr><\/thead>
    Alberto Gabriele, author of Reading Popular Culture in Victorian Print<\/em>, tracks the transnational dissemination of works by author Mary Elizabeth Braddon via the magazine ______ from 1866 to 1899 and distributed throughout the Australian cities of Melbourne, Adelaide, and Hobart; the continental European cities of Brussels, Paris, and Turin; and cities in Turkey, India, and Jamaica, this magazine helped make Braddon’s serialized novels globally available.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

    Which choice completes the text so that it conforms to the conventions of Standard English?<\/strong><\/p>\n\n\n\n

    A. Belgravia<\/em>, published<\/p>\n\n\n\n

    B. Belgravia<\/em> published<\/p>\n\n\n\n

    C. Belgravia<\/em>; published<\/p>\n\n\n\n

    D. Belgravia<\/em>. Published<\/p>\n\n\n\n

    Answer:<\/strong> D<\/strong><\/p>\n\n\n\n

    Skill Tested:<\/strong> Sentence Boundaries & Participial Modifiers<\/p>\n\n\n\n

    Explanation:<\/strong><\/p>\n\n\n\n

    The passage consists of two independent sentences:<\/p>\n\n\n\n

      \n
    1. “Alberto Gabriele … tracks the transnational dissemination of works by author Mary Elizabeth Braddon via the magazine Belgravia.”<\/em><\/li>\n\n\n\n
    2. “Published from 1866 to 1899 and distributed throughout … this magazine helped make Braddon’s serialized novels globally available.”<\/em><\/li>\n<\/ol>\n\n\n\n

      Because the second sentence opens with a long participial modifier (“Published from 1866 to 1899…”<\/em>), the preceding independent sentence must end with a period (D<\/strong>).<\/p>\n\n\n\n

      Question 8<\/strong><\/th><\/tr><\/thead>
      Brothers Orville and Wilbur Wright famously received a patent for their flying machine on May 22, 1906. Louisiana native Charles F. Page, who was born into slavery and self-educated, created a gas-powered flying ship in 1903 that was officially patented on April 10,______ only model had been suspiciously destroyed en route to a planned demonstration at the 1904 World’s Fair, and, discouraged, he never built a replacement.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

      Which choice completes the text so that it conforms to the conventions of Standard English?<\/strong><\/p>\n\n\n\n

      A. 1906 \u2014 roughly six weeks earlier. Page’s<\/p>\n\n\n\n

      B. 1906. Roughly six weeks earlier, Page’s<\/p>\n\n\n\n

      C. 1906 roughly six weeks earlier, Page’s<\/p>\n\n\n\n

      D. 1906 \u2014 roughly six weeks earlier \u2014 Page’s<\/p>\n\n\n\n

      Answer:<\/strong> A<\/strong><\/p>\n\n\n\n

      Skill Tested:<\/strong> Parenthetical Modifiers & Clause Boundaries<\/p>\n\n\n\n

      Explanation:<\/strong><\/p>\n\n\n\n

      The date April 10, 1906, occurred roughly six weeks prior to May 22, 1906. The phrase “roughly six weeks earlier”<\/em> acts as a parenthetical modifier clarifying the relationship between the two dates in the sentence. Setting it off with an em dash (“1906 \u2014 roughly six weeks earlier”<\/em>) completes that modifier, and ending the sentence with a period allows a new independent clause (“Page’s only model had been suspiciously destroyed…”<\/em>) to begin cleanly.<\/p>\n\n\n\n

      Question 9<\/strong><\/th><\/tr><\/thead>
      A single specimen of N. vivans<\/em>, collected at a depth of 129 fathoms (236 meters) in the Indian Ocean, and a single specimen of P. obliquiloculata<\/em>, collected at a depth of 260 fathoms (475 meters) in the South Atlantic, have been preserved as exemplars of their respective _____ former in a repository at Washington, DC’s Museum of Natural History and the latter in a repository at London’s Natural History Museum.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

      Which choice completes the text so that it conforms to the conventions of Standard English?<\/strong><\/p>\n\n\n\n

      A. species. The<\/p>\n\n\n\n

      B. species, the<\/p>\n\n\n\n

      C. species; the<\/p>\n\n\n\n

      D. species, and the<\/p>\n\n\n\n

      Answer:<\/strong> B<\/strong><\/p>\n\n\n\n

      Skill Tested:<\/strong> Appositive Phrases at Clause Ends<\/p>\n\n\n\n

      Explanation:<\/strong><\/p>\n\n\n\n

      The second portion of the sentence (“the former in a repository… and the latter in a repository…”<\/em>) is a compound noun phrase functioning as an appositive that elaborates on “their respective species”<\/em>. An appositive phrase located at the end of a sentence is correctly attached to the main clause using a comma (B<\/strong>).<\/p>\n\n\n\n

      Question 10<\/strong><\/th><\/tr><\/thead>
      Researchers recently theorized that Copper Age (3500 BCE to 2750 BCE) owl-shaped carvings collected from Iberian archaeological sites were likely toys created by children. This hypothesis, based on comparative analyses of owl drawings made by modern children, is supported by the objects predominantly being crafted from slate\u2014a material that, because of its _____ be easily carved by small hands using rudimentary tools.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

      Which choice completes the text so that it conforms to the conventions of Standard English?<\/strong><\/p>\n\n\n\n

      A. malleability\u2014could<\/p>\n\n\n\n

      B. malleability, could<\/p>\n\n\n\n

      C. malleability could<\/p>\n\n\n\n

      D. malleability could\u2014<\/p>\n\n\n\n

      Answer:<\/strong> B<\/strong><\/p>\n\n\n\n

      Skill Tested:<\/strong> Nonessential Prepositional Phrases<\/p>\n\n\n\n

      Explanation:<\/strong><\/p>\n\n\n\n

      Inside the relative clause introduced by “that”<\/em>, the phrase “because of its malleability”<\/em> is an inserted nonessential prepositional modifier. Since it is preceded by a comma after “that”<\/em>, it must be followed by a matching comma before the verb “could”<\/em>: “a material that, because of its malleability, could be easily carved…”<\/em><\/p>\n\n\n\n

      Question 11<\/strong><\/th><\/tr><\/thead>
      In pre-Columbian Mesoamerica, obsidian was used as a commodity currency. By using specific goods like obsidian as common units of exchange, commodity currency economies streamline trade, which is why they often replaced barter economies. Barter economies eschew ______ that requires what economist W.S. Jevons deems a \u201cdouble coincidence of wants\u201d\u2014in other words, each trading party must want precisely what the other has.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

      Which choice completes the text so that it conforms to the conventions of Standard English?<\/strong><\/p>\n\n\n\n

      A. currency, in favor of a direct trade system<\/p>\n\n\n\n

      B. currency in favor of a direct trade system<\/p>\n\n\n\n

      C. currency, in favor of a direct trade system,<\/p>\n\n\n\n

      D. currency\u2014in favor of a direct trade system<\/p>\n\n\n\n

      Answer:<\/strong> B<\/strong><\/p>\n\n\n\n

      Skill Tested:<\/strong> Essential Prepositional Phrases<\/p>\n\n\n\n

      Explanation:<\/strong><\/p>\n\n\n\n

      The phrase “in favor of a direct trade system”<\/em> is essential to the meaning of the verb “eschew”<\/em> (barter economies eschew [X] in favor of [Y]). Setting off “in favor of a direct trade system”<\/em> with commas or dashes would incorrectly turn it into a nonessential element and distort the sentence’s logic.<\/p>\n\n\n\n

      Question 12<\/strong><\/th><\/tr><\/thead>
      For her installation The Last Cruze<\/em>, photographer LaToya Ruby Frazier traveled to Lordstown, Ohio, where she documented the lives of workers at the local automobile plant. In the installation, text culled from a series of in-depth interviews with employees and their families ______ sixty-seven gelatin silver prints, highlighting the collaborative, documentary nature of Frazier’s work.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

      Which choice completes the text so that it conforms to the conventions of Standard English?<\/strong><\/p>\n\n\n\n

      A. punctuating<\/p>\n\n\n\n

      B. are punctuated by<\/p>\n\n\n\n

      C. punctuate<\/p>\n\n\n\n

      D. punctuates<\/p>\n\n\n\n

      Answer:<\/strong> D<\/strong><\/p>\n\n\n\n

      Skill Tested:<\/strong> Subject-Verb Agreement<\/p>\n\n\n\n

      Explanation:<\/strong><\/p>\n\n\n\n

      The singular noun “text”<\/em> is the subject of the clause (“text … punctuates sixty-seven gelatin silver prints”<\/em>). The participle phrase “culled from a series of in-depth interviews with employees and their families”<\/em> acts as a modifier. Therefore, the singular verb “punctuates”<\/em> (D<\/strong>) correctly matches the singular subject “text”<\/em>.<\/p>\n\n\n\n
