Explanation:

Question 1

To find the sentence with the problem, we look for when Laura faces an issue. The sentence "Laura accidentally got black permanent marker on her new, white shirt." describes the problem (stain on new shirt) she encountered.

Laura's research (advice on removing the stain) comes from her friend Lisa, as Lisa gave her the tip about using toothpaste.

We need to list four hard - to - get - out stains. Common ones include ink (other than permanent marker, like ballpoint pen ink), grease (from cooking or oily substances), coffee (stains from spilled coffee), and wine (red wine stains are tough to remove).

Answer:

Laura accidentally got black permanent marker on her new, white shirt.
