mans is so great at explaining these concepts but this handwriting is... atrocious J.Y. LOL still love you!!!!!!

Omg I would love to join!!!

I'm confused on #3 if anyone can provide help. I translated the statement as:

infected --> produce & after one week

As I'm writing this out, I'm beginning to intuit why the "one week" condition actually exists in conjunction with the "infected" condition, but I'm wondering if anyone has a concrete grammatical explanation given that "within one week" appears after the necessary conditional indicator "will?"

Thank you!!!!
