How would a careful rereading of this excerpt help a reader understand the "League" mentioned in the first sentence?

Hello. Unfortunately you did not submit the text that this question refers to. This makes it impossible for it to be answered. However I will try to help you as best I can.

Generally speaking, we can state that the careful reading of the text allows the reader to understand what the "League" is because at some point in the text the activity that this league promotes, or what it means, is presented. In that case, to answer that question, you need to read the text carefully and identify the sentence that promotes a characteristic of that league, which allows you to identify and understand it. This sentence can show what the league does, or has done, who the league members are, what its objective is, among others.

i would say that these are the two thesis statements best for a literary analysis essay on recurring themes in shakespeare's romeo and juliet:

1.  in romeo and juliet, shakespeare demonstrates that love comes in a variety of forms, be it romantic, familial, or between friends.

2.  shakespeare explores the struggle for identity through the character of juliet in his play romeo and juliet.

the other theses aren't reoccurring in this play. 

explanation:

for this case, we must find the number of deaths per day of the year 2015, in automobile accidents, knowing that 32,400 people died.

knowing that the year 2015 had 365 days we have the following division:

where "x" represents the number of deaths per day.

rounding off we have:

approximately, 89 people per day died in 2015

answer:

89 people per day
