Short Answer 
The process involves identifying available science classes at the school, which include Chemistry, Biology, Physics, and Earth Science. It also emphasizes analyzing the language for grammatical accuracy and concludes by eliminating certain options, ultimately selecting answer “D” as the best choice.
Step 1: Identify the Offered Classes
Start by recognizing the specific science classes available at the school. In this case, the school provides a total of four classes:
- Chemistry
- Biology
- Physics
- Earth Science
Step 2: Analyze the Language Used
Next, look at the wording and grammar in the statement. The importance of precise language is evident, as terms like “including”, “are”, “is”, and “such as” may not be appropriate here. This helps in narrowing down the possible answers based on grammatical correctness.
Step 3: Draw a Conclusion Based on Options
Finally, evaluate the available answer choices. Since options “A” and “B” are eliminated due to grammatical issues, and “C” simply suggests ideas rather than forming a list, the logical conclusion points towards selecting answer “D” as the best choice.
