Roberta's science class is going on a field trip, and her teacher asks students to make suggestions about where they should go. Roberta decides to write a letter to her class explaining why they should go to the planetarium.
Roberta decided to begin her letter with this sentence:

The planetarium is not crowded on Wednesdays, so we should visit it then.

Is this sentence an appropriate opening sentence for the purpose of the argument?

A) yes, because it does not give students any other options
B) no, because some students may want to go on a different day
C) no, because it jumps to a supporting reason without clearly stating a stance
D) yes, because it tells students a specific day they can go on the trip

Before introducing the main idea of her letter, Roberta should make a brief introduction about the planetarium and list some arguments about why they should visit the planetarium.

This sentence is not a good way to start her letter, as she jumps directly to a supporting reason without clearly stating a stance because some of her classmates could consider her approach too aggressive and inappropriate.

Each letter should consist of an introduction, where the author will expose his/her ideas politely and concisely, and after that, at the main part, the author should develop his propositions and ideas and represent it adequately. Therefore, Roberta should make a proper introduction and then introduce her proposition of visiting the planetarium.
