Answer the following statement(s) true (T) or false (F)
1. An inertial clock present at two events always measures a shorter time than a pair of synchronized clocks in any inertial reference frame would register between the same two events (as long as the events don’t occur at the same place in that frame). 2.

An observer on the ground will necessarily see (not observe) those blinks to be separated by a larger time interval than a person on the train would.
