Your task is to predict the verdict of a claim based on the provided question-answer pair evidence. The possible labels are: 'Supported', 'Refuted', 'Not Enough Evidence', 'Conflicting Evidence/Cherrypicking'. Justify your answer using the provided evidence and select the correct label.

Claim: Surgical masks were designed and approved for sterile environments. Every time a person puts on their (surgical) mask they are breathing in the germs from everywhere they went. They should be changed or thrown out every 20-30 minutes in a non sterile environment.

Q1: How do surgical masks work?
A1: Surgical face masks are fairly loose-fitting, disposable masks approved by the Food and Drug Administration (FDA) for use as medical devices. Doctors, dentists, and nurses often wear them while treating patients.

These masks prevent large droplets of bodily fluids that may contain viruses or other germs from escaping via the nose and mouth. They also protect against splashes and sprays from other people, such as those from sneezes and coughs.

Q2: How often should surgical masks be changed?
A2: Generally, one time use (one patient encounter)

Q3: Do we need to change the the surgical masks every 20-30 minutes as it  traps the  covid virus and we can breath as well as spread it ?
A3: This is misleading. The person wearing the mask is breathing/coughing/sneezing into the mask and prevents the spread of virus.Surgical masks do not need to be changed out every 20-30 minutes. They need to be changed when they are noticeably dirty or damaged.
