Question

How did the development of the hydrogen bomb affect the arms race?
It decreased the threat of radiation poisoning and sickness.
It increased the danger since it was stronger than an atomic bomb.
It decreased people’s concern about mutually assured destruction.
It increased the number of places suitable for bomb testing.

Answer 1

It increased the danger since it was stronger than an atomic bomb.

The hydrogen (thermonuclear) bomb used fusion to produce far greater explosive yields and destructive power than earlier fission (atomic) bombs, intensifying the arms race, raising stakes of nuclear war, and prompting further weapons development and testing.
