Which best describes President Carter's attempts to free the hostages in Iran?
The first attempt was successful.
O The second attempt was successful.
All of the attempts failed.
O No attempts were made.

All of the attempts failed.

Explanation:

The first attempt was called operation Eagle Claw. This was initiated using 8 helicopters. But 3 of them got shot down and failed to get to the destination.  They needed a minimum of 6 helicopters in order to initiate the rescue mission. Because of this, the first attempt was considered a failure.

The second attempt was called operation Honey Badger. This time, they used more than 50 aircraft to  conduct the rescue mission. But it still ended up in failure.

The hostages were let go during the Reagan's administration, not carter. Soon after Reagan unfreezes around 8 Billion dollars worth of frozen Iranian Assets.
