[AI-generated answer — Bot GPT 3.5]

To find out how many pages Brian can read in 3.5 hours, we can set up a proportion:

Pages / Time = Pages / Time

Let's call x the number of pages Brian can read in 3.5 hours. The proportion becomes:

x / 3.5 = 80 / 2

To solve for x, we can cross multiply:

2x = 80 * 3.5
2x = 280

Now, divide both sides of the equation by 2 to isolate x:

x = 280 / 2
x = 140

Therefore, Brian can read 140 pages in 3.5 hours.

The answer is option B: 140.
