If the choice is true or false, the answer is true. Most of hominins were probably nearly as efficient at bipedal locomotion as humans. However, the bones of their pelvis were shorter from top to bottom than humans. This made their pelvis more stable for weight which supports standing upright or moving bipedially.
The correct option is this: VARIATIONS ARE GREATER OVER LAND THAN OVER WATER.
Temperature variation over water is very small compared to temperature variation over land. This is because, water has high specific heat capacity, which enables it to resist temperature changes when it absorb heat or when it releases heat. A large amount of heat has to be lost or gained before water will show a one degree Celsius temperature change.
