Circle the correct word in the definitions below If you are curious/strange/odd, you want to find out information about something. When a proper/strict/formal attempt is made, it is done officially. If something occurs gradually/suddenly/rarely, it happens over some time. When two things relate/interact/determine, they react to one another. The word specific/detailed/thorough means exact. If there is reappearance/occurrence/repetition, the same thing is done many times. A shell/nucleus/atom is the hard outer part of something that protects what is inside. If somebody predicts/notices/impresses something, they say what they think will happen in the future. If you are discovered/based/impressed by someone, you admire them.
