Question

On the basis of research with young children, a developmental psychologist hypothesized that the skills involved in copying curves must be developed before the skills involved in copying angles can be developed.

Which one of the following, if true, supports the developmental psychologist's hypothesis?

(A) All of the children who can copy curves can also copy straight lines.

(B) All of the children who can copy angles can also copy curves.

(C) The ability to discriminate angles must be developed before angles can be copied.

(D) Some of the children who cannot copy curves can copy angles.

(E) Young children have the cognitive processes involved in copying angles.

The argument proceeds by stating that skills involved in copying curves MUST BE developed before the skills involved in copying angles can be developed. This is exactly what option (B) states - if children possess the ability to copy angles, they must also possess the ability to copy curves

can someone explain why not A?

In my opinion, ability to copy straight lines does not evidently correlate with the ability to copy angles.

Also, it is possible to measure angles between two curved lines.

On the basis of research with young children, a developmental psychologist hypothesized that the skills involved in copying curves must be developed before the skills involved in copying angles can be developed.

Which one of the following, if true, supports the developmental psychologist's hypothesis?

(A) All of the children who can copy curves can also copy straight lines. - WRONG. Opposite to what we are looking for.

(B) All of the children who can copy angles can also copy curves. - CORRECT. If and only if angles are mastered then it can be said that curves too are mastered. In other words, one can say that curves are easier as compared to angles.

(C) The ability to discriminate angles  must be developed before  angles can be copied. - WRONG. Not necessarily true.

(D)  Some  of the children who cannot copy curves can copy angles. - WRONG. Exception case only so not a right choice.

(E) Young children have  the cognitive processes involved in copying angles . - WRONG. May or may not be true. But the differentiation in the passage is not addressed well in this.

Answer B.

can you explain the highlighted part. What exactly are they looking for and how is it the opposite of it?

Bharat010 · Answer

Not talk about straight line apart from this, there is not correlate between curves and angles

djangobackend · Answer

possible counter to B - can we not say that its the copying angles that help with copying curves? it could be that learning to copying angles itself is enough/sufficient to learn copying curves then according to this reasoning, copying curves "First" isn't really useful.

but we are looking for a strengthener and not an assumption, if it were an assumption question then this option will fall due to reasons I gave above. but as a strengthener it only needs to increase our belief in the conclusion and its doing so if ever so slightly by nudging us in the direction that yes it could be that they can copy angles because they can copy curves or curves could be a prerequisite to angles.

LunaticMaestro · Answer

This is a trap choice. The stimulus says nothing about straight lines. Therefore, the option adds not value to us.

Its a kind of out of scope choice.
