My dad asked me a riddle, but I can’t figure it out. He told me that if I can’t solve it myself then I should consult with an AI to figure out the solution.
So, could you please solve the riddle and explain the solution?

Here’s the riddle:

My prefix is food.
My suffix is rude.
My infix comes in rounds.
I keep you off the ground.
What am I?
I consulted an AI, and it gave me the answer as a tire. The explanation is that the prefix "food" refers to the rubber material used in the tire. The suffix "rude" refers to the rough and bumpy texture of the tire when it rolls. The infix "comes in rounds" refers to the circular shape of a tire. And the final line "I keep you off the ground" is a simple explanation of the function of a tire.
You are expected to recognize the named entities of the following text: 

Itamar Rabinovich, who as Israel’s ambassador to Washington conducted unfruitful negotiations with Syria, told Israel Radio looked like Damascus wanted to talk rather than fight.

Named Entities: Itamar Rabinovich, Damascus, Syria, Israel’s ambassador to Washington, Washington, Israel, negotiations

These named entities are correctly identified. Itamar Rabinovich is a man and was Israel's ambassador to the United States during a certain time period. Damascus and Syria are cities and countries, respectively. And Israel and Washington are countries. The negotiations were taking place between Israel and Syria, so both countries are involved in the negotiations.
