Answer: I. The abstract and
II. The discussion
Explanation: An article is a piece of writing on a particular subject which has been published in a journal, newspaper, magazine, on the internet or any form of medium that can be accessed by other people. There are six distinct parts or components in an article and they are:
1. An abstract
2. The introduction
3. The methodology
4. The results
5. The discussion
6. The references
To get a summary of the article, Javier 's lab partner needs to read the abstract which is an overview of the entire article, a summary of the other five components and is usually a few paragraghs; and the discussion where the results are interpreted and compared against existing research or literature review.
These two components give a summary of the entire article.
