Many office buildings designed to prevent outside air from entering have been shown to have elevated levels of various toxic substances circulating through the air inside, a phenomenon known as sick building syndrome. Yet the air in other office buildings does not have elevated levels of these substances, even though those buildings are the same age as the "sick" buildings and have similar designs and ventilation systems.

Which of the following, if true, most helps to explain why not all office buildings designed to prevent outside air from entering have air that contains elevated levels of toxic substances?

A. Certain adhesives and drying agents used in particular types of furniture, carpets, and paint contribute the bulk of the toxic substances that circulate in the air of office buildings.
B. Most office buildings with sick building syndrome were built between 1950 and 1990.
C. Among buildings designed to prevent outside air from entering, houses are no less likely than office buildings to have air that contains elevated levels of toxic substances.
D. The toxic substances that are found in the air of "sick" buildings are substances that are found in at least small quantities in nearly every building.
E. Office buildings with windows that can readily be opened are unlikely to suffer from sick building syndrome.

Difference in elevated levels of toxic substances in buildings with ventilation system preventing outside air to enter ==> toxic substances generated within some of the buildings ==> (A)

Option A explains the difference why air in some buildings has elevated level of toxic substances and other buildings do not.

Although option E is the tempting choice, it fails to explain the difference.

Because, "even though those buildings are the same age as the "sick" buildings and have similar designs and ventilation systems."

The argument believes that sick building syndrome is caused by 'age' ,and design and ventilation systems of buildings. Something along the lines of - something else is causing this syndrome will clear confusion.

air in other office buildings does not have elevated levels of these substances, even though those buildings are the same age as the "sick" buildings and have similar designs and ventilation systems.

They have similar ventilation systems, which points to both of them having windows that can be opened. Since both have windows that can be opened, we still need a reason to explain why some buildings have more toxic air.
So E although extremely tempting, does not help explain the difference.

(A) on the other hands does explain why some buildings have toxic air, as they use certain substances that produce toxic flames.

Hope this helps!

Correct choice is A - Many office buildings designed to prevent outside air from entering have elevated levels of toxic substances in their interior air, but other such buildings similar in age, design, and ventilation do not. So the statement to look for is the one that describes differences in the air quality, designs and ventilation.

Option E does not explain the discrepancy because it is given in the question stem that "sick buildings" have similar designs and ventilation systems.

Option A explains this discrepancy nicely asking it the best choice.

Many office building are found to have sick building syndrome. Yet the air in other office buildings does not have elevated levels of these substances, even though those buildings are the same age as the "sick" buildings and have similar designs and ventilation systems.

Pre-think:

Some thing that will separate both type of buildings. So two similar type of buildings. from where the air inside both these type of builds is coming from. well, both will be having some people in them. but difference will be made if something else is also contributing to this . Sick buildings might have something in them that is increasing the pollution. Option A is on the same lines. Some buildings may have these types of furniture, carpets, and paint, while other buildings similar in age, design, and ventilation do not.
