1. what is the most likely reason the author wrote this article?

to provide an example of how easy it is to win a science award
to explain some surprising uses of household products
to promote an award-winning science fair attended by a young
scientist
to describe an experiment designed and completed by a young
scientist

Explanation:

The article focuses on Nathan Deng's experiment (he wondered about hot water vs cold water in washing and soap's cleaning ability, then did experiments). It's not about how easy to win a science award (the award is just a result of his experiment). There's no main focus on household products' surprising uses. Also, it's not promoting the science fair but rather highlighting Nathan's experiment.

Answer:

To describe an experiment designed and completed by a young scientist.
