A student is writing an argumentative essay for a class. The student wants to revise the draft to improve the development of ideas. Read the draft of the letter and complete the task that follows.

Classrooms should be fragrance–free zones. Fragrances in classrooms cause some students and staff to experience unpleasant side effects. For whatever reason, some people are more sensitive to strong scents in the air than others. These people can experience a very difficult day of school when they are stuck indoors hour after hour inhaling the chemicals found in many different perfumes, cleaning products, whiteboard markers, hand sanitizer, lotions, air fresheners, and others that make them feel ill. Strong scents can contribute to poor and possibly harmful air quality in the classroom.

Schools that have adopted the fragrance–free policy simply ask students and staff to refrain from wearing perfume and cologne, use mild or unscented personal care products, and to use fragrance–free items and cleaners as much as possible. The American Lung Association has written a letter that schools can send home to educate everyone about why scents can be harmful and what can be done to ease the suffering of those who are especially sensitive to chemicals lingering in the air.

Revise the student's draft by choosing the two sentences that give the strongest evidence to support and develop the underlined claim.
A.
The sensitivity to chemicals found in odors can cause headaches, dizziness, difficulty concentrating, numbness, and more.

B.
Some people with allergies and asthma report that certain odors in the confines of shared indoor spaces can trigger intense allergies and/or an asthma attack.

C.
Not everyone likes the same perfumes; just because some people like a certain perfume does not mean everyone will like it.

D.
Schools may experience voices of disapproval when they tell people about the fragrance–free policy, but in time everyone will get used to it.

E.
Of course there are many people who truly enjoy fragrances and do not have any problem with them.
