Explanation:
if we go through each answer we can use process of elimination
A talks about a specific number which sentence two does not use, so it can be eliminated as an answer
C is incorrect because it states how it would "benefit the reader" while in sentence two it talks about how not eating is detrimental and you may not have a choice in it
B is incorrect because it uses the words "dealing" and "avoiding" when the sentence is asking for your "understanding"
D is therefore the correct choice. Furthermore, even without using the process of elimination, using the words "you" and "understand" together in a sentence usually indicates that the writer is attempting says that what they are indicating is very important. The further usage of the secondary pov of the word "you" indicates that they want you to put yourself in that perspective, therefore, making it more personal.
