Explanation:

1. Subject verb agreement implies the subject and verb must agree in number. This means both need to be singular or both need to be plural.
2. Subjects and verbs must AGREE with one another in number (singular or plural).  Therefore, if a subject is singular, its verb should also be singular; if a subject is plural, its verb should also be plural.
3. In present tenses, nouns and verbs form plurals in opposite ways, for example, The dog chases the cat, the dogs chase the cat
4. A phrase or clause between subject and verb does not change the number of the subject, for example, The women, who went for the meeting, were bored
5. Singular indefinite pronoun subjects take singular verbs (anyone, everyone, someone, someone, anybody, somebody, nobody, each, one, either and neither), for example, Each does a good deal of work around the office
6. Plural indefinite pronoun subjects take plural verbs (both, few, many, others, and several).
7. Some indefinite pronouns may be plural or singular (all, any, more, most and some); with countable, use plural, with uncountable, use singular, for example, Some of the sugar is on the floor
8. With compound subjects joined by or/nor, the verb agrees with the subject nearer to it, for example, Neither the directors nor the actors are following the protocols in the meeting
9. Compound subjects joined by and are always plural, for example, An eraser and a pencil make writing easier
10. Inverted Subjects must agree with the verb, for example how are the relative taking up the news?
11. Collective Nouns (jury, group, team,crowd, etc.) may be plural or singular, depending on meaning, for example, The jury has awarded custody to the mother
12. Titles of single entities (organisations, books, countries, etc.) are always singular, for example, The Apples of Hilton is an interesting book to read
13. Plural form subjects with a singular meaning take a singular verb. ( news, mumps, physics, and so on for example, Mumps is a contagious disease). Plural form subjects with singular or plural meaning take a singular or plural verb, depending on meaning. (politics, economics, and so on). Plural form subjects with a plural meaning take a plural verb. (trousers, scissors, for example, The scissors are on the table)
14. With subject and subjective complement of different number, the verb always agrees with the subject, for example,  Poems by WB keats  are my favourite
