Read the passage and answer the question that follows.

no matter what people say, every act of kindness is in fact purely selfish. even large gifts to charity feel good to the giver. whatever beneficial effects to others these gifts produce, it is the personal satisfaction that motivates them. however, this does not mean that charity does no good. on the contrary, selfishly motivated giving has done a lot of good in the world.

which word or phrase from the passage signals a contrasting thought?

It would be the word "however."

This is a transition word, but also a contrasting word could be "on the contrary," but that is reverting back to the original proposition.

The correct answer is: "However."

Explanation:

The passage starts by stating the argument that all acts of kindness are selfish. It continues developing this idea in the following lines and then uses the word "however" to show that the next idea will be contrasting with the first argument: that even though they are selfish acts, they are still good for the world.
