Which sentence has the correct word order? Mike used to listens to folk but now he listen to punk. Mike used to listen to punk but now he listens to folk. __ punk but now he listen to used to folk.

## Step 1
The problem is asking us to identify the sentence that has the correct word order. The word order in English sentences typically follows the Subject-Verb-Object (SVO) structure.

## Step 2
Let's analyze each sentence:

1. "Mike used to listens to folk but now he listen to punk." - This sentence is incorrect because "listens" should be "listen" after "used to", and "listen" should be "listens" in the present tense.

2. "Mike used to listen to punk but now he listens to folk." - This sentence correctly uses "used to" followed by the base form of the verb "listen". It also correctly uses "listens" in the present tense.

3. "punk but now he listen to used to folk." - This sentence is grammatically incorrect and does not make logical sense.

## Step 3
Based on the analysis, the sentence with the correct word order is the second one.
