Answer:
Subject heading
Explanation:
Options you were given are the following:
- Title of the article;
- Volume and page number;
- Author's name and subject heading;
- Subject heading.
Out of the listed, the subject heading is the least likely to help you in locating an article you've already found in the Readers' Guide. Subject headings, which include a word/phrase or a group of words/phrases that most precisely represent what an article is about, are there to help you discover articles in the first place. Since you've already found the article, the subject heading is no longer of use, and other provided information (the title of the article, author's name, and volume and page numbers) should help you locate it.
The most reasonable way to get opinions of experts on any writing topic is doing research at the library... Because: They have so much information there that you can get. On anything and everything. Also, if you need something specific you can find it because everything should be labeled. It shouldn't be hard to find what you are looking for. Sometimes getting information from somewhere else is not true. It can be false, and it can be completely wrong. And trying to get a hold of anyone may be difficult, especially if you want to have an interview with them. They may be busy or may not even respond. So your best choice.. would be just going to the library.
