1. While it is unclear if the Apple Watch itself is the cause of rashes, there are external factors that can lead to these issues, such as wearing the watch too tightly or having allergies.

My primary source comes directly from the community website under Apple. It allows customers to add questions that other users can answer. In the post I found, a user found that the rashes other customers are experiencing might come from the metal the Apple Watch itself uses, or it might be due to wearing the watch band too tightly. However, these users have stated that they have been wearing an Apple watch for 5+ years in the past with no issue, and only recently they been experiencing these rashes, leading them to believe that it has something to do with the Apple watch sensor.

This secondary source I found covers very similar points to those of my primary source. However, they really emphasize that the cause of the rashes is not due to the Apple watch sensor, but due to either allergic reactions to the metals used or to wearing the watch too tightly/lack of cleaning the band. They provide solutions to the rash, such as cleaning the band and moisturizing the skin/over the counter creams to soothe rashes.
4. I think my primary source would have little bias since they are direct comments from community members who have no incentive to add bias, since they really just want solutions to the rashes they are all experiencing. However, my secondary source could definitely have bias since they disregard that it is the Apple watch sensor itself and only really focuses on allergic reactions or bad hygiene.
5. Both my sources support the claim that Apple watches can cause rashes; the original claim is very misleading and doesn't paint the entire picture. It is still unclear whether or not these rashes are directly caused by the sensor itself, since there are so many external factors that the original claim leaves out.
6. None of my evidence necessarily undermines the original claim; it only provides more context that the claim leaves out. However, the essence of the claim is essentially true; it's only phrased misleadingly.
