The best claim is that the reddish-brown substance is not the same as either the fertilizer or the substance that makes up the pipes.

How to decide on a claim?

This prompt requires you to use all the evidence collected in a case about the appearance of a reddish-brown substance in water to identify what this substance is and the cause of it.

What is the best claim?

Based on this, the best claim is that this substance is not the same as either the fertilizer or the substance that makes up the pipes. Here are the reasons:

  • The experiments showed the mysterious substance does not have the same properties as the fertilizer or the material of the pipes, which means it has a different chemical identity.
  • The substance was the result of chemicals in fertilizers reacting with the material of the pipes, which creates a new substance.
