Answer:
A. has some bad information
Step-by-step explanation:
When it comes to words with multiple meanings, we can get hints from the context about their used meaning. This is the case with the word authoritative in our case as well. Authoritative can mean:
- having, characterized by or proceeding from authority;
- commanding and self-confident, likely to be obeyed;
- able to be trusted as accurate, knowledgeable, or reliable.
The used meaning of authoritative in this case is the third one. We can understand that based on the contrast made between the authoritative book and the pamphlet that has some bad information in it. The book is authoritative, especially compared to the faulty pamphlet, which means that it can be trusted as reliable and accurate.
