I have defined the gap in above post. Do you have any specific question. At least give your reasoning.

hey siddharthfrancis,

The statement B says
B)It demonstrates why the biological species concept is invalid.

According to the author, the idea is too restrictive. From this statement, we can easily infer that this idea carries some value; it doesn't matter how much.
So, the biological species concept is not invalid.

Dear siddharthfrancis,
Happy to help here.

Quote:
Which of the following best describes the function of lines 10-13?

Line 10-13: [First, mating between groups labeled as different species (hybridization), as often occurs in the canine family, is quite common in nature.]
To well understand this line, Kindly make sure that you read some part of the passage before and after the line.

Quote:
According to this view, a species is a group of animals that can mate with one another to produce fertile offspring but cannot mate successfully with members of a different group. Yet this idea can be too restrictive.
If I read this line before the highlighted line, the thing that stands out to me is the one mentioned in bold."Yet this idea can be too restrictive". This gives me a gist that author is going to mention some restriction or something that holds back the biological species concept.

First, mating between groups labeled as different species (hybridization), as often occurs in the canine family, is quite common in nature.

Quote:
Second, sometimes the differences between two populations might not prevent them from interbreeding, even though they are dissimilar in traits unrelated to reproduction; some biologists question whether such disparate groups should be considered a single species.
Even though this may be left unread, but if you still read this, it shows that this sentence starts with Second which means that it is to add the point further which is conveyed in the highlighted sentence.
Quote:
B. It develops a point about the biological species concept made in the previous sentence.
The highlighted text in line 10-13 actually adds value/develop/makes concrete the previous sentence "Yet this idea can be too restrictive." The highlighted sentence actually explains one of the three restrictions mentioned, as discussed above. Hence this is correct.
Quote:
E. It demonstrates why the biological species concept is invalid.
While E says it demonstrates why biological species concept is invalid. The passage no where says that the biological species concept is invalid. Though the highlighted text mentions the restriction of biological species concept, but the validity has not been challenged anywhere.
Kindly see the text in the first line of second paragraph, which says "When the biological species concept is difficult to apply" but not invalid....

I hope this helps.
