Answer 1

The question says, which kind of muscle fiber enable the muscle to exert force for a long period of time. The correct option is 'slow switch'. The slow switch muscle enable one to participate in long endurance feats such as long distance running. These muscles are red in colour because of the high quantity of myoglobin found in them.

Answer 2

The correct answer is slow twitch.  

There are generally two types of skeletal muscle fibers present in the body of humans. These are slow twitch fibers and the fast twitch fibers. The slow twitch fibers in the muscle allow the long endurance responses to the muscles, on the other hand, the fast twitch fibers generate a fast response in the muscles.
