Problem 31 - 8 Practice Tests for the ACT 3rd

Question

A. NO CHANGE B. it does have C. they do have D. and they have

Step-by-Step Solution

Answer

Option D is correct if the subject is plural and there is a need to add 'and'. Else, based on the subject, choose A, B or C.

Step 1: Identify the Original Sentence

Look at the part of the sentence that is under review and understand its current form. This ensures clarity of what changes may be necessary.

Step 2: Understand the Context

Read the entire sentence to understand the context and the intended meaning. Determine whether the noun in question is singular or plural and if the subject matches the verb.

Step 3: Evaluate Each Option

Consider each option in the context of the sentence:- Option A (NO CHANGE): Keeps the sentence as it is.- Option B (it does have): Changes the focus to 'it' which implies a singular subject.- Option C (they do have): Changes the focus to 'they' which implies a plural subject.- Option D (and they have): Adds 'and' and changes the subject to 'they,' which should be plural.

Step 4: Match Subject with Verb

Ensure subject-verb agreement. Check if the subject matches the verb form used in the sentence.

Step 5: Choose the Correct Option

After evaluating all options, select the one which maintains the original meaning, ensures clarity, and has correct subject-verb agreement.

Key Concepts

Subject-Verb Agreement

Subject-verb agreement is one of the fundamental rules of English grammar. It ensures that the subject of a sentence matches the verb in number (singular or plural). For example:

• She runs (singular subject + singular verb)
• They run (plural subject + plural verb)

When working on ACT English practice questions, carefully identify whether the subject is singular or plural. Then, check that the verb matches. Misunderstanding this rule can lead to major errors.
In the exercise, you must determine if 'it' (singular) or 'they' (plural) is the right subject. If the original sentence has a singular subject, Option B (it does have) would be correct. If the subject is plural, then Option C (they do have) or D (and they have) could be correct, depending on context.

Contextual Understanding

Understanding the context of a sentence is key to selecting the right answer. Context provides clues about the intended meaning and ensures that your choice fits naturally within the sentence. Ask yourself these questions:

• What is the overall theme or topic of the text?
• What is the subject being discussed?
• Does my choice maintain the sentence’s original meaning?

For example, in the provided exercise, reading the entire sentence helps to understand if the subject is singular or plural. This also helps to determine if an additional conjunction like 'and' is required, which makes Option D sometimes a better choice. Evaluate the purpose each part of the sentence serves to maintain the context consistently.

Sentence Evaluation

Evaluating a sentence involves examining its structure and flow. Each part should work together to convey a clear and coherent thought. Here is a checklist for evaluating sentences:

• Does the sentence have a clear subject and predicate?
• Is the sentence grammatically correct?
• Does it make sense within the paragraph or text as a whole?
• Is there proper punctuation?

In the example exercise, once you have identified the subject and understood the context, evaluate each option to determine which one maintains correct structure and meaning. Option A may sometimes be correct if no adjustment is needed. However, a common mistake is to overlook better alternatives that enhance clarity and coherence. Therefore, after identifying your options, choose the one that best fits in terms of subject-verb agreement and contextual understanding.
