This question came in the Dhaka university admission exam 2015-16

Q) Counting is a combination of several skills, each _______ on the other

(a) building

(b) reinforcing

(c) shaping

(d) improving

I think that the answer is probably (a). Question bank says the answer is (c). Which is the correct answer?

  • In Indian English, is "shaping on" commonly used? What do any of the proposed solutions really mean where "counting skills" are concerned?

  • Did you copy the question precisely? I would think it should be "each one ..... on the other"

    Great find, I suppose each is sufficient on its own, so "each one" is redundant. Guess what? The answer supplied is indeed "building". blog.learntube.academy/…

1 Answer 1


You are right. You build on things. I've never heard the expression shaping on and I don't think it's correct, either. I would go a step further: I'm familiar with the notion of shaping things. It's the presence of the word on that I think is flat wrong.
