CR 1 Which of the following most logically completes the argument?
In a recent article, a health expert has claimed that the toxins used by fumigators remain in a house or office for long periods of time, and not only kill pests, but also damage the health of human inhabitants. For example, Chlorpyrifos, an active ingredient in fumigation pesticides, leads to acute lung damage. The article has met with much opposition including claims that almost all wall paints continually release nanoparticles that are known to be equally harmful to the lungs. These objections to the article should not be taken into account since __________.
A. paints are not always required to undergo toxin level analyses before receiving authorization for distribution
B. they are mostly supported by companies with financial interests in Chlorpyrifos production or fumigation services
C. the combined damage caused by Chlorpyrifos and the nanoparticles is more detrimental than that of the nanoparticles alone
D. the molecular structure of paint nanoparticles is very different to that of Chlorpyrifos
E. the polymers used in some decorative wall paints are actually more likely to cause acute lung damage than Chlorpyrifos

CR 2 A specific species of African monkey performs an elaborate rain dance after the first rain. The fact that the actual movements which the monkeys of this species perform differ depending on the troop's location in Africa has led zoologists to believe that the dance comprises of specific movements that are a cultural rather than a genetic development.Which of the following, if true, would most strengthen the conclusion drawn by the zoologists?A. Each separate species of African monkey performs a different dance after the first rain.B. There is a known case of a monkey of the mentioned species raised among monkeys of a different species that would perform a dance different from that performed by his adopting group after the first rain.C. A recent zoological report was published describing ant-luring technique differences between separate groups of the same species of monkey as based on the type of ant prevalent in the monkey's specific habitat.D. An infant monkey raised in captivity would move about slightly after the first rain of the year, but its movements did not resemble those of any of the groups found throughout Africa.E. The dance comprises of movements that are very similar when comparing troops of the same species.
