In a monogamous culture, 100% of the adults are married. The average number of children per family is five and over-population is a threat. Programs to encourage birth-control have been ineffective. It has been suggested that this failure is due to these programs ignoring a tradition that values male children very highly, so that every parent wants to have at least one son. It is proposed that couples be encouraged to use birth-control measures after the birth of their first son.

If this proposal is widely accepted in the culture, we may expect that:

(A) the rate of population increase will be slowed, and future generations will contain a disproportionately high number of females.

(B) the rate of population increase will be slowed, and the gender balance in future generations will remain as it is at present.

(C) the rate of population growth will remain the same, and future generations will contain a disproportionately high number of females.

(D) there will be no significant effect either on population growth or on gender balance.

(E) the population will decline precipitously, because approximately half of all families will have only a single child.

Radio Stations with radio data system (RDS) technology broadcast special program information that only radios with an RDS feature can receive. Between 1994 and 1996, the number of RDS radio stations in Verdland increased from 250 to 600. However, since the number of RDS equipped radios in Verdland was about the same in 1996 as in 1994, the number of Verdlanders receiving the special program information probably did not increase significantly.

Which of the following is an assumption on which the argument depends?

(A) Few if any of the RDS radio stations that began broadcasting in Verdland after 1994 broadcast to people with RDS-equipped radios living in areas not previously reached by RDS stations.

(B) In 1996 Verdlanders who lived within the listening area of an RDS station already had a radio equipped to receive RDS.

(C) Equipping a radio station with RDS technology does not decrease the station’s listening area.

(D) In 1996 Verdlanders who did not own radios equipped to receive RDS could not receive any programming from the RDS radio stations that began broadcasting in Verdland after 1994.

(E) The RDS radio stations in Verdland in 1996 did not all offer the same type of programming.

Insect infestations in certain cotton-growing regions of the world have caused dramatic increases in the price of cotton on the world market. By contrast, the price of soybeans has long remained stable.

Which of the following, if true, most seriously weakens the plan’s chances for success?

(A) The cost of raising soybeans has increased significantly over the past several years and is expected to continue to climb.

(B) Tests of a newly developed, inexpensive pesticide have shown it to be both environmentally safe and effective against the insects that have infested cotton crops.

(C) In the past several years, there has been no sharp increase in the demand for cotton and for goods made out of cotton.

(D) Few consumers would be willing to pay significantly higher prices for cotton goods than they are now paying.
