Try asking questions and find things you have in common say hi, my name is insert name! What’s your name? Then things start coming in easily
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"

No they aren't proper to use in writing class they are considered slang. It would show your teacher that your not interested in sounding educated and proper.
Hope this helps!
