Brief Explanations:

The sentence "In this paragraph, I will describe NASA's $18 billion budget for 2015" is considered a weak topic sentence because it is an announcement of intent rather than a claim or an argument. A strong topic sentence should present a specific point of view or an arguable claim that the rest of the paragraph supports. Simply stating what you are going to do (using "I will describe") lacks an analytical assertion or a central idea that requires evidence or persuasion.

Answer:

Weak: Not a Claim
