Critical Reasoning

In 2009, a private school spent $200,000 on a building which housed classrooms, offices, and a library. In 2010, the school was unable to earn a profit. Therefore, the principal should be fired.

Each of the following, if true, weakens the author's conclusion EXCEPT:

The principal was hired primarily for her unique ability to establish a strong sense of community, which many parents cited as a quality that kept children enrolled in the school longer.
The new library also features a seating area big enough for all students to participate in cultural arts performances which the head of school intends to schedule more frequently now.
The principal was hired when the construction of the new building was almost completed.
A significant number of families left the school in 2010 because a favorite teacher retired.
More than half of the new families who joined the school in 2010 cited the beautiful new school facility as an important factor in their selection of the school.

A - incorrect (does weaken the argument), if the principal had been hired because of his special skills to make the community stronger, the fact whether the school earns a profit is of less significance
B - correct, the fact that the new library is relatively spacious does not mean that the principal is not expected to make the school earn a profit
C - incorrect, the principal cannot be held responsible for the decisions taken before he started work
D - incorrect,similarly to the situation described in C, it is not the principal's fault that a favorite teacher retired and many families left school
E- incorrect, lower profit in 2010 may be a temporary problem, since parents like the new facility
