choose the correct meaning of the roots and prefixes

b. can be (done)

1. -able, -ible

a. step

b. can be (done)

Explanation:

Question 15:

The word "regress" means to go back or deteriorate (e.g., in development or quality). "Improve" is the opposite, so the correct option is b.

The root "Grad, Gres" is related to steps or movement (e.g., "graduate" implies moving step - by - step in education, "progress" means moving forward step - by - step). So its meaning is "step", so the correct option is a.

The suffixes "-able" and "-ible" (spelled as - ible here as - ible) mean "capable of being" or "can be (done)". For example, "readable" means "can be read", "flexible" means "can be flexed". So the correct option is b.

Answer:

b. deteriorate
