@Madelyn-Luskey Winifred's explanation of how some bees use various other means to navigate is meant to show that there is an established pattern in nature where bees may use multiple ways to convey the same information, supporting Winifred's claim. This is what B says.
E on the other hand says that she's proposing an alternative explanation. An alternative explanation here would likely be more about the various reasons bees may dance other than conveying information about food locations. Instead, she's simply disagreeing with Henry's assertion that there is a different reason, saying that there is not.

Great point @anita. I also picked E and I was confused. The general principle that W is trying to bring evidence to, is that there can be multiple methods of animal communication. E is more specific about trying to explain the specific reason of why they dance.
