What is the implicit meaning of this passage?

nick bumped into arif at the grocery store. "hi, arif," said nick. "ali and i have an extra ticket to the concert this weekend. do you want to go? ""maybe some other time," said arif, walking away.

"of course," said arif. "what time should i stop by your house? "

a. nick trusts arif

b. nick thinks arif is irresponsible.

c. arif is afraid of dogs.

d. arif does not like nick.

The right answer is the A) Nick trusts Arif.

Explanation: There are no references to dogs in the passage, and Arif seems to have changed his mind and have accepted Nick's invitation to the concert, so options D and C are incorrect. In addition, it cannot be inferred that Nick thinks that Arif is irresponsible, since he is inviting him to go with him and another friend to a concert, so option B should be eliminated as well. Therefore, and since Nick seems to be genuinely inviting Arif to a concert, and presumably meeting with him at his house, it can be inferred that he trusts Arif.
