Can someone pls help What should have been the only independent variable in Paola’s experiment?

A) the amount of water
B) the amount of sugar
C) the form of the sugar
D) the temperature of the water

The whale was a missile blasting from beneath the surface.  2.) a majestic whale leapt skyward before diving back into the sea.    these are both figurative language. this is so because the whale in sentence "1" was not actually a missile, nor was it actually blasting. now, for sentence "2", a whale can not actually "leap".
