Common Information

In response to the increasing environmental damage wrought by poachers, authorities placed a ban on ivory in the 1980s. Although the ban resulted in an initial decrease in the sale and trade of illegal ivory and a concurrent increase in the elephant population, more pressing needs caused most Western nations to withdraw funding for poaching prevention programs. Without significant financial support, poorer countries were unable to effectively combat poachers. The resulting explosion in the ivory trade has seen prices increase to nearly 10 times the $45 per pound price at the beginning of the decade.

Unfortunately, the countries with the worst poaching problems have also tended to be the ones least able to combat the problem due to unstable political systems, corruption, lack of comprehensive enforcement programs, or some combination of all these factors. One primary hindrance to better enforcement of the ivory ban came from an inability to definitively identify the country of origin of illegal ivory. 

Countries used this uncertainty to avoid responsibility for curbing illegal poaching in their territories by attempting to blame other countries for the oversights in enforcement. Now, though, zoologists have perfected a new DNA identification system. First, scientists gathered genetic data from the population of African elephants, an arduous effort that ultimately resulted in a detailed DNA-based map of the distribution of African elephants. Then, the researchers developed a method to extract DNA evidence from ivory, allowing them to match the ivory with elephant populations on the map. Zoologists hope this new method will pinpoint the exact origin of poached ivory and force countries to accept their responsibility in enforcing the ban.

Q.

Common Information Question: 1/4

The passage suggests which of the following about the ivory ban?

 A.

It has been mostly unsuccessful in reducing the trade of illegal ivory.

 B.

It will be successful now that the DNA-based map has been developed.

 C.

Western countries will increase their funding of the program now that countries are forced to take responsibility for the poaching occurring within their borders.

 D.

Western monetary support was a major factor in its success.

 E.

It will continue to be ineffective unless the problems of political corruption are solved.

 Hide Ans

Solution:
Option(D) is correct

This is an inference question. Look for the answer in the beginning of the passage, where the ivory ban is first introduced.

The passage states "Although the ban resulted in an initial decrease in the sale and trade of illegal ivory and a concurrent increase in the elephant population, more pressing needs caused most Western nations to withdraw funding for poaching prevention programs.

Without significant financial support, poorer countries were unable to effectively combat poachers." Thus, choice D is the best.

Choice A goes too far because the passage states that the ban was successful at first.

Choice B isn’t necessarily true, so it cannot be an inference.

Choice C is not stated or implied; there is no prediction of what Western countries will do.

Choice E goes beyond the scope of the passage - no mention of future outcomes is discussed.
