Eight Legged Freaks

Question: Do the spiders grow big because of the food that they are fed, or because of the chemicals spilled in the water?

Chosen answer: Both! The owner of the spider farm was feeding the spiders bugs from the water that had the chemical spill in it. The bugs were contaminated with the chemical, thus contaminating the spiders. Note: The man who owned the spider farm had no idea about the contaminated water.
