Answer:
Which sentence is the topic sentence? 3
Which sentence is the concluding sentence? 4
Which sentence does not support the topic of the paragraph? 7
Step-by-step explanation:
It's very simple to understand, The conclusion sentence should either restate the topic sentence or just wrap everything up. It makes the most sense that the topic sentence is 3 because it's a generic sentence, whereas the other sentences are supporting details. If the topic of the paragraph is 3, 7 is the sentence that does not support that topic.
Sorry if any of these are wrong!
