While proponents argue about the benefits of vaccination for children,

In E
How is the second statement a observation ? Its a fact .

Whereas i dont find anything wrong with B

In option B, it says, 'the second does not dispute that position. In more direct words, it can be interpreted as 'the second agrees with that position'.
So does it agree? No, the two statements can be seen as two separate premises not supporting each other but supporting the conclusion.

Even if you consider second as fact, it fits only in option E.

Kudos if helpful!

the second does not dispute that position -- doesn't mean it agrees with that position

Even I marked B for same reason

The second statement is like an evidence that there is data to claim that getting vaccinated is not of much use

First stmnt says there is no much data to claim that vaccinations are effective

So as per B stmnt 2 does not oppose the stmnt 1

Hey akshata19 not an expert but here are my two cents

In option B BF1 is not the position the argument as a whole seeks to establish (this line states that BF1 is the main conclusion of the argument) It is not the main conclusion of the argument. This is the main conclusion : So, there is hardly any improvement in the prevention rate because of vaccination..

As for BF2 : the second does not dispute that position : this part is correct

the option is wrong cause of BF1

A) The first describes the circumstance that the argument as a whole seeks to explain; the second provides a statement that the argument as a whole seeks to establish.

The first describes the circumstance
Yes. We can call it a current situation or circumstance.
that the argument as a whole seeks to explain;
No. The purpose of the argument is not to explain why there is hardly any data available.
the second provides a statement
Yes.
that the argument as a whole seeks to establish.
No. The second boldface is a fact. The argument cannot establish a fact. The fact is being used to establish the main conclusion.


Thus, this is not the correct answer choice.


B) The first describes the position that the argument as a whole seeks to establish; the second does not dispute that position.

The first describes the position
No. It states an observation and not a conclusion or position taken by someone.
that the argument as a whole seeks to establish;
No. This is not the main conclusion of the argument.
the second does not dispute that position.
Yes. BF2 does not go against BF1 although it is not a conclusion.


Thus, this is not the correct answer choice.


C) The first describes the evidence in support of the main conclusion of the argument; the second states that conclusion.

The first describes the evidence
Yes. Since this fact or observation has been used to support a conclusion, we can call it evidence.
in support of the main conclusion of the argument;
Yes.
the second states that conclusion.
No. BF2 is a fact and not the main conclusion.


Thus, this is not the correct answer choice.


D) The first is the position that the argument as a whole opposes; the second provides evidence against the position being opposed.

The first is the position
No. It is an observation, not a conclusion and so cannot be called a position.
that the argument as a whole opposes;
No. The argument does not go against this observation.
the second provides evidence
Yes. Since this fact or observation has been used to support a conclusion, we can call it evidence.
against the position being opposed.
No. BF2 does not go against BF1.

Thus, this is not the correct answer choice.


E) The first and second both state observations that support jointly the conclusion of the argument as a whole.

The first and second both state observations
Yes. They are facts observed by the author.
that support jointly the conclusion of the argument as a whole.
Yes. They support the main conclusion.


Thus, this is the correct answer choice.

How can the lack of any claim implies that there is no improvement?
