"Η θερμοκρασία του νερού."

Translation: The temperature of the water.

[UralMasha]

Why is "the water temperature" wrong answer?

[Tony979198]

It should be accepted. That is the normal way of talking.

I wrote: The temperature of water. Why was it marked wrong? Is there a different Greek translation for "of water" and "of the water"?
