SAT form, structure, and sense questions: how to answer them

Subject-verb agreement, pronouns, verb tense and form, possessives and plurals, and modifiers.

Practise form, structure, and sense →Timed module

What the question looks like

Each question has its own short text (a passage, a pair of texts, a table or a student's notes) and four options. The usual question is: Which choice completes the text so that it conforms to the conventions of Standard English?

How to answer it

  1. Find the true subject: cross out prepositional phrases and descriptive clauses.
  2. Check the time words for tense ('last spring', 'by the time').
  3. For an opening phrase like 'Having spent...', the very next noun must be the one doing it.
  4. For pronouns and possessives, find the noun they refer to and check number.

Common traps

In the harder second module

Hard questions use inverted sentences ('Among the artifacts was...'), 'neither... nor', 'together with', and collective nouns.

Every rule tested is in the grammar rules reference.

Worked example

Worked example (easier)

Each of the students in the robotics club ______ a different part of the robot.

Which choice completes the text so that it conforms to the conventions of Standard English?

  1. are building
  2. build
  3. builds
  4. have built

Answer: C: builds

The subject is 'Each', which is singular ('of the students in the robotics club' is a prepositional phrase). A singular subject takes the singular verb 'builds'.

Why the other options are wrong

  • A: 'are building' is plural.
  • B: 'build' is plural and does not agree with 'Each'.
  • D: 'have built' is plural.

Practice questions

Try each one before you open the answer. Every answer explains why the right option is right and why each of the other three is wrong. Answers to the first 4 are open to everyone; the rest need only a free account. Questions use American English, as the SAT does.

Question 1 (medium)

The bakery's owners decided to expand after ______ sourdough won first prize at the state fair.

Which choice completes the text so that it conforms to the conventions of Standard English?

  1. they're
  2. there
  3. their
  4. its
Show the answer and why each option is right or wrong

Answer: C: their

The sourdough belongs to the owners (plural), so the plural possessive 'their' is correct.

Why the other options are wrong

  • A: 'they're' means 'they are'.
  • B: 'there' refers to a place.
  • D: 'its' is singular; the antecedent 'owners' is plural.

Question 2 (hard)

The collection of letters, journals, and photographs that the historian donated to the university ______ now available to researchers online.

Which choice completes the text so that it conforms to the conventions of Standard English?

  1. were
  2. is
  3. have been
  4. are
Show the answer and why each option is right or wrong

Answer: B: is

The subject is 'The collection', which is singular; 'of letters, journals, and photographs' and the 'that' clause only describe it. So 'is'.

Why the other options are wrong

  • A: 'were' is plural and also past tense, which clashes with 'now'.
  • C: 'have been' is plural.
  • D: 'are' agrees with the nearby plural nouns, not the true subject 'collection'.

Question 3 (hard)

The new species of frog, found only on a single mountain in Peru, ______ its eggs on leaves that hang over streams, so that the tadpoles drop straight into the water when they hatch.

Which choice completes the text so that it conforms to the conventions of Standard English?

  1. laying
  2. lay
  3. to lay
  4. lays
Show the answer and why each option is right or wrong

Answer: D: lays

The subject 'The new species of frog' is singular and needs a main verb. 'lays' is the singular present tense of 'lay' (to put down).

Why the other options are wrong

  • A: 'laying' is not a main verb, which leaves the sentence without one.
  • B: 'lay' is the plural present form and does not agree with the singular subject 'species'.
  • C: 'to lay' is an infinitive, which also leaves the sentence without a main verb.

Question 4 (hard)

The novelist, whose early books ______ largely ignored by critics, is now widely regarded as one of the most important writers of her generation.

Which choice completes the text so that it conforms to the conventions of Standard English?

  1. has been
  2. is
  3. were
  4. was
Show the answer and why each option is right or wrong

Answer: C: were

Inside the 'whose' clause, the subject is 'early books' (plural), and the past context calls for 'were'.

Why the other options are wrong

  • A: 'has been' is singular.
  • B: 'is' is singular and present tense.
  • D: 'was' is singular.
