Question

a frogs slime can kill some strains.
a medieval remedy can help get rid of them.
phages can attack the bacterial cells.
problem\tsolution
people get the flu.\t
people get mrsa infections.\t
people get skin infections caused by pseudomonas.\t

Explanation:

To solve this, we analyze each problem and match it with the appropriate solution based on the nature of the problem (flu is a viral infection, MRSA is a bacterial infection, Pseudomonas is a bacterium, and the solutions relate to bacterial/fungal or specific remedies):

1. People get the flu: Flu is caused by a virus. The medieval remedy (likely related to traditional treatments for viral/respiratory issues or general illness) is a possible match, but let's check others. Wait, no—flu is viral, but the other solutions are about bacteria. Wait, maybe the medieval remedy is for flu? Or maybe I misread. Wait, the top solutions: frog slime kills some strains (bacteria), medieval remedy (maybe for flu or other), phages attack bacterial cells.

Wait, let's re-express:

• Flu: Viral, so the medieval remedy (which could be a traditional treatment for flu) might be the solution. So "A medieval remedy can help get rid of them."

• MRSA infections: MRSA is a bacterium. Phages attack bacterial cells, so "Phages can attack the bacterial cells."

• Skin infections by Pseudomonas: Pseudomonas is a bacterium. Frog's slime can kill some strains (of bacteria), so "A frog’s slime can kill some strains."

Answer:

• People get the flu: A medieval remedy can help get rid of them.
• People get MRSA infections: Phages can attack the bacterial cells.
• People get skin infections caused by Pseudomonas: A frog’s slime can kill some strains.
