Praxis Core Grammar and Usage Summary

The subject is "box," which is singular, so the verb must be "was." The words "of old photographs" only describe the box; they are not the subject.

Wrong choices

• "photographs": "Photographs" is the correct plural form; it is part of the phrase that describes the box.
• "after": "After" correctly shows the order of events.
• "moved": "Moved" is the correct past tense for an action that already happened.
• "No error": There is an error: "were" does not agree with the singular subject "box."

"Me and Tom" is the subject of the verb "carpooled," so it needs the subject pronoun: "Tom and I carpooled." Test it by dropping Tom: you would say "I carpooled," not "Me carpooled."

Wrong choices

• "because": "Because" correctly gives the reason for carpooling.
• "was": "Was" agrees with the singular subject "center."
• "our": "Our" is the correct possessive form here.
• "No error": There is an error: "Me" cannot be the subject of a verb.

"Yesterday" and "visited" place the events in the past, so the second verb must also be past tense: "the students wrote."

Wrong choices

• "visited": "Visited" is past tense, which matches "yesterday."
• "then": "Then" correctly shows the order of events.
• "about": "About" is the correct preposition after "report."
• "No error": There is an error: "write" is present tense in a sentence about yesterday.

The lessons belong to the teachers, so the possessive word "their" is needed. "There" refers to a place.

Wrong choices

• "have": "Have" is the correct verb after "will."
• "effect": "Effect" is correctly used as a noun meaning "result."
• "how": "How" correctly begins the phrase "how teachers plan."
• "No error": There is an error: "there" should be "their."

The pronoun replaces "proposals," which is plural, so it must be "them," not "it."

Wrong choices

• "reviewed": "Reviewed" is the correct past tense and matches "returned."
• "carefully": "Carefully" is an adverb that correctly describes how they reviewed.
• "with": "With" is the correct preposition before "written comments."
• "No error": There is an error: "it" does not agree with the plural noun "proposals."

With "neither ... nor," the verb agrees with the subject closest to it. The closest subject is "students" (plural), so "were" is correct. "Rang" is the correct past tense of "ring." The sentence has no error.

Wrong choices

• "were": "Were" agrees with "students," the subject nearest the verb, so it is correct.
• "when": "When" correctly tells the time of the surprise.
• "rang": "Rang" is the correct simple past form of "ring" ("rung" needs a helper such as "had").
• "during": "During" correctly means "in the time of" the test.

"Quick" describes how the students adjusted, which is an action (a verb). A word that describes a verb must be an adverb, so it should be "adjusted quickly."

Wrong choices

• "of": "Of" correctly links "routine" and "the school."
• "and": A comma plus "and" correctly joins two complete sentences.
• "were": "Were" agrees with the plural subject "they."
• "No error": There is an error: "quick" should be the adverb "quickly."

Only two programs are compared, so the sentence needs "more effective." "Most" is used when comparing three or more things.

Wrong choices

• "is": "Is" agrees with the singular subject "one."
• "according to": "According to" correctly names the source of the information.
• "own": "Own" is used correctly to stress that the data belong to the district.
• "No error": There is an error: "the most" should be "the more" because only two things are compared.

In standard English, a person "insists on" something. "Insisted for" is not the accepted idiom, so it should be "insisted on a meeting."

Wrong choices

• "said": "Said" is the correct past tense of "say."
• "opposed": "Opposed" is the correct word to describe being against the change.
• "to": "Opposed to" is the standard idiom, so "to" is correct.
• "No error": There is an error: the idiom is "insisted on," not "insisted for."

"To lie" means to rest or recline and takes no object; "to lay" means to put something down and needs an object. The coach was resting, so it should be "After lying down."

Wrong choices

• "felt": "Felt" is correct; "felt well" correctly describes the coach's health.
• "to return": "To return" is the correct verb form after "well enough."
• "practice": "Practice" is correctly used as a noun here.
• "No error": There is an error: "laying" should be "lying."
