Show Answer Key & Explanations Step-by-step solution for: How To Write A Topic Sentence Worksheet
Here is the solution to the worksheet, with a clear topic sentence for each paragraph that states its main idea:

---

1. Janice’s vegetable garden failed due to pests and disease, so she plans to study gardening over the winter to improve next year.

*Explanation:*
The paragraph describes multiple failures in Janice’s garden — tomatoes with blossom end rot, squash killed by vine borers, eggplants destroyed by potato beetles. Her disappointment leads to a resolution: studying gardening to do better next year. The topic sentence summarizes this cause-and-effect outcome: failure → decision to learn → future improvement.

---

2. Allen’s hard work on the hockey team paid off when he was named Most Valuable Player after scoring key goals early in the season.

*Explanation:*
The paragraph highlights Allen’s performance (6 goals, then 3 more) and culminates in his recognition as MVP. The concluding sentence — “All of his hard work had definitely paid off!” — is the core message. The topic sentence captures both his effort and the reward, making it the central idea.

---

3. Rachel’s consistent diligence and talent in math have earned her academic recognition, tutoring opportunities, and scholarship nominations.

*Explanation:*
This paragraph lists several achievements stemming from Rachel’s responsible habits (doing homework on time) and natural ability (talent in math). These lead to being selected for advanced programs and nominated for scholarships. The topic sentence ties these outcomes together under the umbrella of her diligence and talent — the main idea driving all the examples.

Final Answer Summary:

1. Janice’s vegetable garden failed due to pests and disease, so she plans to study gardening over the winter to improve next year.
