I guess that all you have to do is focus, don't procrastinate. Shut off anything that might distract you, like put away your phone. Don't even listen to music, because sometimes that just breaks concentration. Considering how you've been trying to study for the past 2 hours, try taking a break. And continue to take short breaks so you don't get too tired!
I hope this helped haha! I've had far too much experience with the same issue.

False, because in his writings, Thoreau has this:
"Some of my pleasantest hours were during the long rainstorms... which confined me to the house for the afternoon.."
So from this you can reason that he saw these afternoon storms as enjoyable and pleasant to him.
Thus the answer is false.
