analyze genomes

Is it [spoiler](C)[/spoiler]?
From the passage, we cannot certainly infer Option D...

Rest all options seem to be unconnected to the passage

what is the OA?

The ability to analyze genomes - sequences of DNA - has grown more and more sophisticated. Scientists are able to examine the biological past in finer detail and with greater accuracy. A new analysis of the genetic links between early humans and chimpanzees has led to a hypothesis that the two species diverged more recently than previous estimates indicated. This gives credence to a very startling new theory: the ancestors of humans and chimpanzees might have hybridized to produce the lineage from which modern humans eventually developed.

What can be inferred from the statements above?

A: Hybridized species combine the best of both lineages.
B: Political and religious pressures will affect the course of future research.
C: Future research will enable scientists to determine the exact characteristics of this hybrid ancestor of modern man.
D: Earlier genome analysis established genetic links between early humans and chimpanzees.
E: Human DNA is more complex than that of chimpanzees.

Please explain.

The answer should be D .

This is an inference question so we need to consider the statements in the passage as true and any out side information that can not be verified from the passage will be incorrect .

Lets look at the options :

A: Hybridized species combine the best of both lineages.
[The passage talks about Hybridized species but it combines the best of both lineage we dont know .]
B: Political and religious pressures will affect the course of future research.
[Political and religious pressures - never mentioned in the passage ]
C: Future research will enable scientists to determine the exact characteristics of this hybrid ancestor of modern man.
[The passage dose not talk about the future and drawing an inference about the future will be far fetched]
D: Earlier genome analysis established genetic links between early humans and chimpanzees.
[This is correct.If we look at the passage it states
"A new analysis of the genetic links between early humans and chimpanzees has led to a hypothesis that the two species diverged more recently than previous estimates indicated."
This means the link was established earlier but the accuracy of estimation was not correct and is rectified by current analysis.]
E: Human DNA is more complex than that of chimpanzees.
[again some thing that can not be verified from the passage.]

It is D, very simple by POE

C -> an inference can't say something about FUTURE. so reject.

IMO __D.

As erxplained by Rockey...
