[Giappv]

The light suddenly went out and I couldn't see anything, but little by little my eyes ......... to the darkness.

(a) adapted
(b) fitted
(c) accommodated
(d) matched
Please explain for me this answer?

Thank you.

Hi Giappv

Have a look at the explanation that accompanies this test as well as some of the other explanations in the synonyms tests:

Here is a dictionary definition for 'adapt':

In other words, when a person's eyes adapt to a lack of light, the eyes gradually change. This would generally mean that the pupils dilate (become larger):

Hi Amy,

Thank you for your answer.
I looked at the links you send me, the dictionary is really useful.
I think "adapt" means the change happens naturally and "accommodate" means the change need an action from people?
Is that right?
