116. Approximately 7.6 million women who earn incomes have preschool-age children, and approximately 6.4 million women are the sole income earners for their families. These figures indicate that there are comparatively few income-earning women who have preschool-age children but are not the sole income earners for their families.

A major flaw in the reasoning is that it

(A) relies on figures that are too imprecise to support the conclusion drawn

(B) overlooks the possibility that there is little or no overlap between the two populations of women cited

(C) fails to indicate whether the difference between the two figures cited will tend to remain stable over time

(D) ignores the possibility that families with preschool-age children might also have older children

(E) provides no information on families in which men are the sole income earners

why the anawer is b?

119. For a television program about astrology, investigators went into the street and found twenty volunteers born under the sign of Gemini who were willing to be interviewed on the program and to take a personality test. The test confirmed the investigators’ personal impressions that each of the volunteers was more sociable and extroverted than people are on average. This modest investigation thus supports the claim that one’s astrological birth sign influences one’s personality.

Which one of the following, if true, indicates the most serious flaw in the method used by the investigators?

(A) The personality test was not administered or scored personally by the investigators.

(B) People born under astrological signs other than Gemini have been judged by astrologers to be much less sociable than those born under Gemini.

(C) The personal impressions the investigators first formed of other people have tended to be confirmed by the investigators’ late experience of those people.

(D) There is not likely to be a greater proportion of people born under the sign of Gemini on the street than in the population as a whole.

(E) People who are not sociable and extroverted are not likely to agree to participate in such an investigation.

why the answer is e? i think this answer support the conculsion.
