Matt, Erin, and Lauren were having a challenge to see who could dissolve a one-pound cube of sugar the quickest.

Matt puts his sugar cube in a bucket of water and stirs it with a wooden spoon. Erin heats up the water before putting it into her bucket and uses a wood spoon to stir it.

What must Lauren do to make her sugar cube dissolve quicker than Matt and Erin?

A) Place the sugar cube into a bucket of cold water and stir really, really fast.

B) Place the sugar cube into a bucket of hotter water and stir slower than Matt and Erin.

C) Get a smaller container with less water and put the sugar cube in it and shake it.

D) Break the sugar cube into smaller pieces, put into hot water and stir it.
