Answer and Explanation:
Hello. You didn't show the answer options, nor did you say what the students think about school subjects, which makes it impossible for me to answer your question efficiently. However, I will help you as much as I can, showing you how to recognize a sentence that should be placed in the introduction of an opinion article. I hope it helps.
The introduction of an article is the moment when the author must present his theme and make it very clear what he will talk about during the article. Literally, the main subject of the article is introduced in this section. In this case, the student should put in the introduction exactly his opinion about school subjects, showing the position he will defend in the rest of the article.
Example: Schools have failed to provide disciplines that are really important for the academic development of all students, who have spent time on irrelevant and worthless subjects.
