GRAMMAR (Questions 1-40)
1. Which sentence is grammatically correct?
A) Who's coming to the party?
B) Whose to blame for the economy?
C) Who's hat is this?
D) Whose going to vote?
Answer: A) Who's coming to the party?
Rationale: "Who's" is a contraction of "who is" or "who has." In option A,
"who's coming" means "who is coming" . Options B, C, and D incorrectly
use "who's" or "whose." "Whose" indicates possession, so "Whose hat is
this?" would be correct, but "Who's hat" is incorrect.
2. Which sentence uses the correct form of "to/too/two"?
A) I went two the store.
B) I want ice cream, too.
C) The nurse gave him too shorts.
D) I want to know your name.
,Answer: B) I want ice cream, too.
Rationale: "Too" means "also" or "excessively." Option B correctly uses
"too" to mean "also." Option A incorrectly uses "two" for "to," option C
incorrectly uses "too" for "two," and option D is grammatically correct but
doesn't address the distinction in the question .
3. Which sentence is grammatically correct?
A) He did well on his diet.
B) He done well on his diet.
C) He did good on his diet.
D) He done good on his diet.
Answer: A) He did well on his diet.
Rationale: "Well" is an adverb modifying the verb "did," while "good" is an
adjective. "Done" is a past participle and requires a helping verb; "did" is
the correct past tense of "do" .
4. Which sentence demonstrates correct pronoun agreement?
A) Several lost his or her keys on the train.
B) Does everyone have their train tickets ready?
C) Is everyone ready for their ice-cream sundaes?
D) Somebody left his or her jacket on the train.
Answer: D) Somebody left his or her jacket on the train.
Rationale: "Somebody" is singular and requires singular pronouns. While
"their" is commonly used in casual speech, formal grammar requires "his or
her" for singular indefinite pronouns .
5. Which sentence should replace the following incorrect sentence?
"This door to remain unlocked when occupied."
,A) This door will remain unlocked when the office is occupied.
B) This door to remain unclosed while open.
C) This sentence is correct as written.
D) This office must have the door unlocked at all times.
Answer: A) This door will remain unlocked when the office is occupied.
Rationale: The original sentence lacks a verb. Option A adds the future
tense verb "will remain" and clarifies that the door belongs to an office.
Option B still lacks a proper verb, and option D changes the meaning .
6. Which sentence is grammatically correct?
A) Sarah plays her new saxophone well.
B) The dog catches the freebee good.
C) The band did good during the halftime show.
D) The band that played before ours was well.
Answer: A) Sarah plays her new saxophone well.
Rationale: "Well" is an adverb modifying the verb "plays," correctly
describing how Sarah plays. "Good" is an adjective and cannot modify
verbs .
7. Which use of apostrophe is correct in the sentence? "Because of
staff change's, the list of birthday's was distributed to all worker's in
the business' three offices."
A) Change's
B) Worker's
C) Business'
D) Birthday's
Answer: C) Business'
, Rationale: "Business'" shows possession for a singular noun ending in "s."
The other options incorrectly use apostrophes for plurals. "Changes,"
"workers," and "birthdays" are plural nouns requiring no apostrophe .
8. Which sentence uses the correct form of "their/there/they're"?
A) The patient told the nurse, "put the flowers on that table over their."
B) The students looked at their test scores.
C) Their comes a time when one chooses between right and wrong.
D) Their waiting for you.
Answer: B) The students looked at their test scores.
Rationale: "Their" is possessive, correctly used to show the test scores
belong to the students. "There" indicates location, and "they're" is a
contraction of "they are" .
9. Arrange alphabetically: VERBAL, VOLUME, VOID, VITAL.
A) Vital, verbal, void, volume
B) Verbal, vital, void, volume
C) Verbal, volume, void, vital
D) Vital, verbal, volume, void
Answer: B) Verbal, vital, void, volume
Rationale: Alphabetical order compares letters sequentially: Ve, Vi, Vo.
"Verbal" and "vital" both begin with "V" but "er" comes before "it." Then
"void" and "volume" both start with "vo," but "i" comes before "l" .
10. Identify the incomplete sentence.
A) While they were sleeping.
B) Everything worked out all right.
