Comprehensive grammar test covering the rules for using 'either/or' and 'neither/nor' in singular and plural contexts.

Task Explanation:

The task involves completing sentences using the correct forms of either/or and neither/nor. These conjunctions are used to connect two items, and the verb agreement depends on whether the subject is singular or plural.

#### Key Rules:
1. Neither/Nor:
- Follows the rule of subject-verb agreement: The verb agrees with the subject closest to it.
- If the closest subject is singular, use a singular verb.
- If the closest subject is plural, use a plural verb.

2. Either/Or:
- Also follows the rule of subject-verb agreement: The verb agrees with the subject closest to it.
- If the closest subject is singular, use a singular verb.
- If the closest subject is plural, use a plural verb.

3. Placement in Sentences:
- Neither/Nor is used to indicate that none of the two options are true.
- Either/Or is used to indicate that one of the two options is true.
