2. False

I say true. Please recheck my answer.

Yes, true.

To determine whether your answer is correct, let's break down the question and analyze it.

The question states that all sentences in a paragraph must relate to the idea introduced by the topic sentence. In other words, every sentence within a paragraph should support or provide further information about the main idea presented in the topic sentence.

To verify your answer, we can evaluate the purpose of a topic sentence. The topic sentence is the primary sentence that expresses the main idea or the central point of the paragraph. It acts as a guide for the reader, informing them of the subject or purpose of the paragraph.

To check if all sentences in a paragraph should relate to the topic sentence, let's consider an example:

Topic sentence: Dogs are loyal and loving companions.
Sentence 1: Dogs provide emotional support to their owners.
Sentence 2: They can also be trained to assist those with disabilities.
Sentence 3: Additionally, their loyalty makes them excellent family pets.
Sentence 4: Dogs require proper care and regular exercise.

In this example, we can observe that all the sentences (1-4) within the paragraph relate to the main idea introduced in the topic sentence. Each sentence provides additional information or supports the primary idea, creating a cohesive and logically connected paragraph.

Therefore, based on this analysis, the statement "All sentences in a paragraph must relate to the idea that the topic sentence in the paragraph introduces" is true.
