hi teacher I want to ask a question. After reading question I want to hear your opinion about the question.

according to figures,world population is increasing _____ in _____ highly industrialized countries.
A)the slowest/as
B)slower/most
C)the most slowly/the more
D)slowly/such as
E)the slower/the most

Welcome.

A) and D) don't fit: "as" and "such as" don't work in that context.
E) doesn't fit: "the slower" is a noun phrase.

That leaves us with choices B) and D), both of which sound awkward to my ears. But let's look at the grammar anyway:

B) slower/most
C) the most slowly/the more

"slower" is a comparative; e.g., ... is increasing slower than ..., whereas "the most slowly" doesn't require "than"; e.g., the most slowly increasing ... / ... increasing the most slowly.

All the best.
