(B) While it is possible that once the restrictions are lifted, U.S. companies
will want to hire more scientists and will seek them overseas, there are too
many unknowns between the given premises and this conclusion. It is
doubtful that an increase in the number of immigrating stem cell research
scientists would have a “significant” impact on the number of “foreign
professionals” overall.
(C) This passage is about government restrictions; no information is given
about “financial backing.” Beware of extreme statements such as “in all parts
of the world.”
(D) No information is given concerning the current or future position of the
United States in terms of stem cell research. Though restrictions and scientists
switching companies are two issues related to a company’s prosperity, there is
no information about how these issues directly affect the position of the
United States.
(E) No information is given that would predict the behavior of the scientists in
the future.
43.
(D).
In the argument, the critics mistake correlation for causation. While it
is true that most employees were reassigned to the mission to Mars, it is not
established that the mission to Europa was scrapped to move the employees to
a different project; it’s possible that some other motivation caused the demise
of the Europa project. NASA claims that its critics are misinformed.
(A) Irrelevant. The conclusion is based on the critics’ assumption of
causation, and this choice fails to address the issue of the motivations
underlying NASA’s decision-making process. That the percentage of spending
is going to decrease could indicate many possible scenarios, including that
NASA is unhappy with the progress of the project and plans to cut future
spending or that the organization expects the development of the shuttle to be
completed by 2018.
(B) Weakens. If public interest determines its budget, NASA has strong
motivation to keep public interest high. Additionally, “budget” is not
mentioned in the original argument.
(C) Irrelevant. This statement differentiates between the opinions of some
scientists and the opinions of others, but sheds no light on the motivations
behind NASA’s decisions.
