Question

to read conscientiously means to read with
a help
b care
c speed

Explanation:

The word "conscientiously" means to do something with great care, thoroughness, and a sense of responsibility. So, to read conscientiously means to read with care. Option A "help" doesn't fit the meaning of "conscientiously" in the context of reading. Option C "speed" also doesn't relate to the meaning of reading conscientiously (reading with speed would be "read quickly" or similar, not conscientiously).

Answer:

B. care
