Choose the odd one out from the following terms and name the category to which the others belong:
Used bandages, Pesticides, Face masks, Syringes.
Topic: Biomedical waste
Answer
Odd one out: PESTICIDES. Category of the others: BIOMEDICAL (hospital) WASTES.
Used bandages, face masks and syringes are all BIOMEDICAL WASTE — generated in hospitals, clinics and laboratories during the treatment of patients. They are infectious and must be incinerated or autoclaved rather than dumped.
PESTICIDES are AGRICULTURAL chemicals used to kill insects and weeds. They are certainly pollutants, but of farmland and water bodies, not of hospitals.
THE CARE NEEDED: all four are pollutants, so "pollutants" is not a category that separates three from one. The category must be the narrower one — biomedical waste. Whenever every term shares an obvious label, look for a finer one.
