Did you spot this pseudo-plural singular subject Stop Sign?

Very good!

This answer choice is grammatically incorrect. The plural subject crises does not agree with the singular verb is.

When you read the original sentence, did you spot the pseudo-plural singular subject Stop Sign ?

This answer choice repeats the original mistake. The singular subject crisis does not agree with the plural verb are.

Did you spot this Stop Sign?

That's probably why you made this mistake.

It is important to memorize Stop Signs as they help us solve questions quickly and efficiently. Once we identify the Stop Sign in a Sentence Correction question, we know what to look for in the answer choices.

The Stop Sign "A Pseudo Plural Subject" indicates a subject which appears to be plural but is actually singular. This means that when we encounter such a subject, we ought to make sure that the verb which refers to this subject agrees with it, i.e., it is a singular verb.

In this case, are is the verb which refers to crisis, but does not agree with it, since are is a plural verb. The mistake can be corrected by using either a singular subject and a singular verb (crisis is) or a plural subject and a plural verb (crises are).

Excellent. What did you do next?

Unfortunately, doing so caused you to eliminate the correct answer.

When we find a Subject Verb Agreement mistake and both the subject and the verb are underlined, we cannot assume that the answer choices will change only the verb or only the subject. We must examine both subject and verb and look for an answer choice in which they agree.

Now, did you notice that crisis in the original sentence was changed into crises in this answer choice?

We can see now that although the verb was changed into singular, there is still a Subject Verb Agreement mistake since the subject was changed into plural.

As you surely know by now, crises is the plural form of the crisis.

Therefore, the plural subject crises does not agree with is, which is a singular verb.

Now, did you notice that the word are in the original sentence was changed into is in this answer choice?

We can see now that although the subject was changed into the plural crises, there is still a subject Verb Agreement mistake here, since the verb was changed into the singular is.

Is is the singular form of the verb to be (are is the plural form).

Therefore, is does not agree with crises, which is a plural subject.
