Final answer:
The verb 'cry' is a regular verb, and its plural form is 'cries'. The review questions require selecting the correct form of the verb based on subject-verb agreement rules, taking into account the subjects and conjunctions in each sentence.
Step-by-step explanation:
The verb 'cry' is a regular verb in the English language, which means it follows the standard pattern of forming the past tense and past participle by adding '-ed' or '-d'. To rewrite the word 'cry' in the plural form, you would change the 'y' to 'i' and add '-es', making it 'cries'.
Now, let's answer the review questions regarding the form of the verb in given sentences:
- There are fewer criminals on the street since the law was passed.
- That may be, but there is no evidence that it's making us any safer.
- Mathematics is the fundamental language of psychics.
- Jerry, who runs around all weekend trying to find great deals at big-box stores, sometimes loses sight of what's really important.
- Civics is taught in every high school in America.

When it comes to subject-verb agreement, singular subjects take singular verbs, and plural subjects take plural verbs. Certain conjunctions, such as 'and', 'or', and 'nor', can also determine whether a verb should be singular or plural.
