What is the meaning of the word slake?

The word "slake" means to satisfy or relieve, particularly in the context of thirst or desire. When you slake your thirst, you are quenching it or satisfying that need for hydration. This usage typically implies an easing or alleviation of something that requires fulfillment, like a craving or a strong need.

In contrast, the other choices do not align with this meaning. For instance, to enhance refers to improving or augmenting something, which does not relate to the idea of satisfaction or relief. To endure denotes a sense of suffering through difficulties without giving up, unrelated to the concept of gratification. Finally, to lengthen is about increasing the duration or size of something, which also does not connect with satisfying or relieving a desire or need.
