I just discovered a 3.5 MSun main-sequence star orbiting a 2.5 MSun red giant. I'll bet that red giant was more massive than 2.5 MSun when it was a main-sequence star. Part A Decide whether the statement makes sense (or is clearly true) or does not make sense (or is clearly false) and choose the correct explanation. Decide whether the statement makes sense (or is clearly true) or does not make sense (or is clearly false) and choose the correct explanation. This statement is sensible. The 2.5MSun red giant had to be more massive than its companion at some point in the past in order for it to be more advanced in its evolutionary state than its companion. This statement does not make sense.

Two horses begin at rest. after a few seconds, horse a is traveling with a velocity of 10 m/s west, while horse b is traveling with a velocity of 13 m/s west. which horse had a greater acceleration? a. horse a because its change in velocity was greater than horse b's in the same time. b. horse b because its change in velocity was greater than horse a's in the same time. c. horse b because its change in velocity was the same as horse a's, but it took less time. d. both horses had the same acceleration.
