Choose the most suitable option to replace the highlighted part of the sentence: The police is investigating the matter seriously.
- (a)are investigating the matter seriously
- (b)investigates the matter
- (c)were investigating seriously the matter
- (d)is in investigation
Answer
Why
Correct — A. The subject is police, a noun that is plural in English although it has no -s: the police are, the police have.
So the singular is has to become are. The rest of the highlighted part is sound and stays in place: investigating the matter seriously.
Plural verb, same tense, same word order: option (a).
Why the others are wrong
- (b)investigates the matter — Investigates is singular, the same agreement error as is. It also turns the ongoing action into a simple present and drops seriously.
- (c)were investigating seriously the matter — Were fixes the number but moves the action into the past for no reason, and seriously now sits between the verb and its object, the matter.
- (d)is in investigation — Is keeps the agreement error. The idiom is under investigation, and it describes the thing being investigated, not the investigators; the matter also disappears.
Concept
Some nouns are plural without a plural ending. Police, cattle and people all take a plural verb: the police have arrested two men, the cattle are grazing, people are waiting.
That sets police apart from a collective noun such as committee or team, which can take a singular verb when the group acts as one unit.
For one member of the force, English uses police officer, which is singular.
Key facts
- Police is a plural noun: the police are, the police have.
- Cattle and people also take plural verbs.
- Adverbs of manner do not normally go between a verb and its object: investigating the matter seriously, not investigating seriously the matter.
- One member of the force is a police officer, which takes a singular verb.

Common traps
- Treating police like team or committee and keeping is because it names one body.
- Fixing the verb but accepting an option that also changes the tense or the word order.
