Answer: In modern view, the origin of variation is mutation. Since Darwin stated that variation will occurs in the most useful part and is retained, most people don't use their left hands, if according to Darwin's theory, those left hands should be going to extinct by now.
If Darwin's theory of variation is acceptable, then dwarfs who always want to be giant, by stretching the body, would have become giant by now.
Darwin just had a general idea about variation, offsprings tends to change in appearance from the parents. But this variation is not in terms of usefulness of the body parts of the parents, it is in terms of Gene mutation of the parents in their offspring.
Explanation: Darwin's 1859 theory set out a theory of Evolution by natural selection to explain adaptation and speciation.
According to Darwin's theory, individual of one generation are qualitatively different from one another this is as a result of natural selection. But in modern science, this is as a result of Gene mutation.

Answer: C. foreign goods to be more expensive to residents of foreign nations
Explanation: When the dollar price rises in a country that the official currency is not the dollar, purchase of foreign goods becomes expensive.
For example, if in a country like Nigeria, 1 dollar equals 360 Naira and a resident has been purchasing goods outside Nigeria using the dollars, if 1 dollar increases to 400 naira, that becomes more expensive for the Nigerian (foreigner). Because the Nigerian now have to cough out 400 naira for 1 dollar as against the for 360 naira for 1 dollar.
