Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. discoveries.
- In the context of the sentence, where Darwin is planning to write a book, "discoveries" is the most suitable term.
- It indicates that the book would describe the findings or significant observations made by Darwin.
- The other options ("facts," "articles," "failures") do not fit the context as well.
