Hey there,
Your question states: <span>Which choice most effectively displays the concept of comparison and contrast?
Based on my understanding, the best option from your answers choices above,your correct answer would be </span>

. My reason on why I say that the answer would be "<span>While they are almost the same size, Earth and Venus have very different terrains." is basically because this would be a good compare and contrast. The other options have no click to it to make a concept of making a compare and contrast. Your correct answer would be D.
Correct answer : "</span><span>While they are almost the same size, Earth and Venus have very different terrains"

The second one. Cody and Aleena are the antecedents and <em>their</em> is the pronoun referring back to them.
Hope this helps ☺️
A new study is the first to compare professional electronic sport (esport) players with recreational video game players and explores the similarities and differences between what motivates each group. While the two groups are psychosocially different, they found that both esport and recreational gamers run the risk of developing internet gaming disorder when their intense immersion in the activity is tied to escapism.
