Everybody loves own dog better than other people’s dogs.

their

Explanation:

"Their" means belonging to that person. You don't say "everyone loves that own dog." This doesn't make sense.

"Everyone" means all the people. "Their" goes with a thing or things belonging to people, while "that" is referring to the person, not what belongs to them.

no its not a run on sentence however i think you meant wet suits not sours also a run on sentence would be like surfers surf all winter long in southern california by using wet sours to keep them warm and the live their all year long  

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.
