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: 3/4

The passage suggests which of the following about the DNA-based map created by zoologists?

 A.

The map is able to pinpoint the exact elephant from which poached ivory was obtained.

 B.

Its assemblage involved a great deal of work on the part of the researchers.

 C.

Its creation will force countries to accept responsibility for the ivory poached from within their borders.

 D.

It allows zoologists to keep track of the migration patterns of African elephants.

 E.

It must be updated constantly to account for changes in elephant populations.

 Hide Ans

Solution:
Option(B) is correct

This is an inference question. Read the lines about the DNA- based map in the second half of the final paragraph.

It states "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." The author uses the word "arduous" to describe the effort, so choice B is a valid inference.

Choice A goes too far because the map allows the researchers to track populations, but not individual elephants.

Choice C is not necessarily true.

Choice D and E might be true but are not supported by information in the passage.

the anser to this question is a direct answer and not based on inference... "arduous" word describe that the research was a tedious one... so the question must be modified...or the answer should be C) as its exactly what given in the passage
