Find the thesis: 1. Edward seemed like an average student, but on
weekends Edward packed his bag, boarded an airplane,
and travelled the world. Being a young musician and a
college student was hard work.

2. Future cars will not need human drivers. Imagine
giving orders to empty drivers' seats.

3. Some establishments, such as McDonalds and
Starbucks, offer free wi-fi to attract larger crowds. Are
fast food restaurants encouraging obesity?

halibut, flounder, tuna, and trout are all fish. so your first answer is 1.) fish. and since fish is edible, your next answer would be 3). edible

to describe those fishes more thoroughly, some of those fishes live in fresh water, and some of the fishes live in salt water, and that is not a thing that they all have in common. the question is asking what is common with all of the fish, so answer choices 2). fresh water and 4). salt water are not right.

i believe that the answer is b! i hope i out!

it makes the game seem more impressive.
