To slake means to do what?

The term "slake" refers to the act of satisfying or relieving, particularly in relation to thirst or desire. It is often used in contexts where one quenches a thirst or satisfies a need, like slaking one's thirst with water. The essence of "slake" captures the idea of providing some form of fulfillment or alleviation.

Understanding this context makes it clear why "satisfy or relieve" is the most fitting definition among the options. The other choices present concepts that diverge from this meaning; for instance, increasing tension or complicating matters counters the notion of relief, while silencing does not encompass the idea of fulfillment or satisfaction, specifically in the context that "slake" is commonly used. This underscores how integral the notion of satisfaction is to the meaning of "slake."
