Question

what is that for ? I asked. (change to direct)​

Answer 1

Answer:

"What is that for?", "I asked".

Explanation:

While converting to direct we should keep in mind to add the quotation marks ("").  

Direct or quoted speech is spoken or written text that reports speech or thought in its original form phrased by the original speaker; in narrative, it is usually enclosed in quotation marks but can be enclosed in guillemets.

THEN: what is that for ? I asked.

NOW: "What is that for?", "I asked".
