Identify the Topic Sentence – Solution and Explanation

The goal of this worksheet is to identify the topic sentence in each paragraph. A topic sentence expresses the main idea of the paragraph. It can appear at the beginning, middle, or end, but it usually introduces what the rest of the paragraph will discuss.

Let’s go through each paragraph one by one.

---

#### Paragraph 1:
> Many people think poetry is old-fashioned and uninteresting. They don't realize that every time they hear a song sung, they are hearing poetry in the form of song lyrics. Just like many written poems, many song lyrics use rhythm, rhyme, and literary imagery. It turns out that poetry isn't old-fashioned; it's as modern as the latest hit song!

- Main Idea: Poetry is not outdated — it's alive in modern music.
- The first sentence states a common misconception: *Many people think poetry is old-fashioned and uninteresting.*
- But the rest of the paragraph argues against this idea by showing how song lyrics are a form of poetry.
- The last sentence summarizes the main point: *"It turns out that poetry isn't old-fashioned; it's as modern as the latest hit song!"*

✔ Topic Sentence:
"It turns out that poetry isn't old-fashioned; it's as modern as the latest hit song!"

➡️ This is the best choice because it captures the overall message of the paragraph. Even though the paragraph starts with a contrast, the final sentence clearly states the main idea.

#### Paragraph 2:
> Growing a garden can be fun, good exercise, and will provide fresh fruits and vegetables for the gardener. It is interesting to watch the seeds pop their heads above the soil for the first time. It is sometimes hard to believe that a little seed can become a large vine or plant in just a few weeks. Planting the seeds and pulling weeds are good exercise for anyone. Then, after watching the plant grow and produce, the gardener ends up with delicious tomatoes, beans, or other yummy produce from the garden.

- Main Idea: Gardening has many benefits — fun, exercise, and food.
- The first sentence lists all three benefits: fun, exercise, fresh produce.
- All the following sentences support this idea:
- Watching seeds grow → fun
- Planting and weeding → exercise
- Harvesting tomatoes/beans → fresh food

✔ Topic Sentence:
"Growing a garden can be fun, good exercise, and will provide fresh fruits and vegetables for the gardener."

➡️ This sentence is clear, concise, and directly states the main idea. The rest of the paragraph provides supporting details.

#### Paragraph 3:
> Sometimes it is hard to fall asleep. Maybe you are not sleepy, or maybe you are thinking about what happened during the day. You can also lie awake if a big event, like a test or a party, is happening the next day. There are several things you can do to try and fall asleep. You can try counting sheep, or just counting, which will keep your mind busy with a repetitious activity. Sometimes listening to soft music or gentle sounds, like rain, helps. You can even try telling yourself a story, which may distract your mind enough that you will be asleep in no time.

- Main Idea: It's common to have trouble sleeping, and there are ways to help.
- The first sentence introduces the problem: *Sometimes it is hard to fall asleep.*
- The next few sentences explain why (not sleepy, overthinking, upcoming events).
- Then, the paragraph shifts to solutions: counting, music, storytelling.
- So, the paragraph covers both the problem and solutions.

But which sentence best captures the main idea?

Let’s compare:

- First sentence: "Sometimes it is hard to fall asleep." → This is part of the idea, but doesn’t mention solutions.
- Later sentence: "There are several things you can do to try and fall asleep." → This introduces the main purpose of the paragraph: offering strategies.

Wait — actually, the main focus seems to shift from the problem to how to fix it.

But notice: the paragraph starts with the problem and then moves into solutions. The central idea is that people often struggle to sleep, but there are helpful techniques.

So, the best topic sentence should reflect both aspects.

But the most comprehensive sentence that sets up the whole paragraph is:

✔ "Sometimes it is hard to fall asleep."

➡️ Why? Because it introduces the main issue, and the rest of the paragraph explains why and what to do about it. While the later sentence ("There are several things...") is important, it's more of a supporting idea than the main topic.

However, some might argue that the purpose of the paragraph is to give sleep tips, so the topic sentence should be about solutions.

But since the paragraph begins with the problem and uses the tips to address it, the first sentence is still the best topic sentence — it sets the stage.

Alternatively, if we're looking for the sentence that best summarizes the entire paragraph, it might be a combination, but since only one sentence can be selected, and the first sentence introduces the core theme, it's the most appropriate.

✔ Final Answer: "Sometimes it is hard to fall asleep."

🔍 How to Identify a Topic Sentence:

1. Ask: What is the main idea of the paragraph?
2. Look for a sentence that summarizes the rest.
3. Check if the other sentences support it.
4. It can be at the beginning, middle, or end, but it must state the central point.
