Sample questions with answers and explanations

Sample 1

"The cat is on the mat." What is the prepositional phrase in the sentence?

Answer: D

A prepositional phrase starts with a preposition and ends with a noun or pronoun (its object). "On" is the preposition; "the mat" is the object. Put together, "on the mat" tells us where the cat is. That whole chunk is the prepositional phrase.

Tip: Prepositional phrase = preposition + (the) + noun. Often answers "where? when? how?"

Why the other choices are wrong
  • A. "The" alone is just a determiner, not a phrase.
  • B. "Cat" is a noun and the subject, not a prepositional phrase.
  • C. "Is" is a linking verb, not a phrase.

Sample 2

The faculty _______ divided on the issue of the new curriculum implementation scheduled for next semester.

Answer: B

Collective nouns (faculty, team, staff, family) can take either singular or plural verbs depending on context. If the collective is acting as a single unit, use singular: 'The faculty approves the new policy.' If the members are acting separately or in disagreement, use plural: 'The faculty are divided on the new curriculum.' The word 'divided' is the key clue here—it shows the members are acting individually with different opinions, so the verb shifts to plural 'are.' This is a subtle rule that trips up even native speakers, and understanding when to use 'is' versus 'are' with collectives is crucial for professional writing.

Why the other choices are wrong
  • A. Singular 'is' would work only if the faculty acted as one unified group.
  • C. The past tense 'was' is incorrect in the present-tense context of the sentence.
  • D. 'Has' is present tense but third-person singular, and does not fit the plural context indicated by 'divided.'

Sample 3

Identify the mood of the verb in the following sentence: 'If I were the president, I would prioritize education funding.'

Answer: C

The subjunctive mood signals something not real — a wish, hypothesis, or condition contrary to fact. The classic English marker is using 'were' instead of 'was' with singular subjects: 'If I WERE you' (subjunctive) vs. 'I WAS late' (indicative). The example 'If I were the president' is hypothetical — the speaker isn't actually president — so subjunctive is the right call. Modern English has lost most of its subjunctive forms; this 'were' construction is one of the few that survives.

Why the other choices are wrong
  • A. Indicative is the mood for stating facts ('I AM the president'). The example is hypothetical, not factual.
  • B. Imperative gives commands ('Be the president!'). The example is a conditional statement, not an order.
  • D. Infinitive isn't a mood — it's the unmarked base form of the verb ('to be').
