Q17 - Henry: Some scientists explain

[kingofclubs323]

Would someone explain why answer choice B is correct? I'm getting stuck on what the "general claim" is.

[a.andreoli88]

Winifred's Conclusion:
[It is not necessarily true that all animals only have one way of communicating a certain kind of information (i.e., honeybees can use both scent and dance to communicate food location).]

Winifred goes on to give an example about bees in general in support of his conclusion, and then follows up with a specific example about honeybees.

Winifred's conclusion is our "general claim" and the role played by the navigation of bees is our example in support of our conclusion/general claim.

A bit wordy question, and it is asking for what Role specific parts of the stimulus play in Winifred's argument.

Here is the Core:

(Henry)
Some scientist explains the dance of honeybees as a means to communicate location of food source + Honeybees do not need that complicated mechanism + Forager honeybees simply leave a scent trail for food location.
==>
there must be some other explanation for the honeybee’s dance.

(Winifred)
Most animals have several ways for accomplishing special tasks + Bees of some species navigate using other means and honeybees could use scent trail as a supplementary means of communication. + Similarly, scent trails are a supplementary not an exclusive means of communicating.
==>
honeybee's dance could still be an explanation / means for indicating food source.

@ Henry is assuming that there is only one way to communicate food location. Since there is one way (scent trail) not as complicated as honeybee dance, unnecessarily complicated honeybee dance is NOT a means for communication, but there is some other explanation for it. What if they both are used for communication? Maybe honeybee dance is used when it is raining, so scent trail couldn't be left?

Winifred is attacking this assumption and raises a possibility of having several ways for special tasks. Here, especially W uses a comparison with an aspect of “navigation” to make a point that bees could use several ways for certain tasks. (or is this an analogy? or a comparison?) “How bees of some species navigate” plays a role of a premise and evidence as a comparison / analogy that supports his conclusion.

Here are the answer choice analyses.

A) No ambiguity present.

B) "Similarly" is an indicator that "navigation" aspect has been stated to support W's conclusion via comparison / analogy.

C) Winifred brings in a new information dealing a different aspect of bees' behavior and doesn't say anything about Henry's evidence. So, no influence on accuracy of Henry's evidence.

D) Like mentioned in C), directly contradicting Henry's conclusion is not what Winifred is doing. He/she brings up other possibility and undermines Henry's conclusion by attacking his assumption.

E) If this were to be true, Winifred would be agreeing to Henry. But Winifred is raising a doubt on Henry's argument.
