Answers:
1. B
走狗 (zǒugǒu): hired thug, lackey.
遛狗 (liùgǒu): walk the dog.
训狗 (xùngǒu): train a dog.
So B is the correct answer.
2. B.
好的 (hǎo de): Okay.
好吃 (hǎo chī): good to eat; tasty; delicious.
These two words above can not be filled in the sentence“饭做_____吗？”. They are not matched in Chinese.
Verb + 好 (hǎo) + 了 (le), to show completion of an action
In the sentence “饭做好了吗？(Fàn zuò hǎo le ma?),” “做 (zuò)”is a verb meaning “to do(cook).” The whole sentence means “Have you completed the action of cooking?” or, “Have you finished cooking?” So B is the correct answer.
