Mr. Holmes sure likes to play with Legos now that he is staying home these days. He was thinking that nuclear reactions were just like playing with lego pieces. Here are his three ideas why legos are like nuclear reactions. 1. If he builds a project that is too big, it will fall apart on its own because the connections are not strong enough to hold the pieces together.

2. Putting smaller lego pieces together to create bigger objects provides Mr. Holmes lots and lots of energy. He could keep doing this for a very long time.

3. While it causes a mess, Mr. Holmes gains energy by taking large objects and smashing them into smaller objects. While this is fun, it only lasts a limited time, because the large objects to smash are pretty scarce.

Which of the following reactions nuclear reactions is Mr. Holmes thinking of in this scenario?
