Answer:
C- a book entitled What Every Fisherman Needs to Know
Step-by-step explanation:
A) Is just about sharks, so this wouldn't help Tom.
B) Is a poem, and probably wouldn't have much factual or straightforward information for Tom to use.
C) Is a book literally titled 'what every fisherman needs to know'. This book will most likely give Tom a wide range of information that is centered around his topic of interest.
D) Might be factual, but the information is about a tournament, and not fishing itself. There could also be the problem of bias, so any fishing information may not be reliable.
So C) is the best answer.
