Where did Dad say the industrial toxins he tested seemed to come from?

Where did Dad say the industrial toxins he tested seemed to come from?

• A. Print Shop
• B. Newspaper
• C. Library
• D. Warehouse

Answer: (A)

The scenario points to chemicals associated with printing—inks and the solvents used to mix and clean them. If Dad’s tests showed compounds typical of those printing-related chemicals, the most plausible source is the place where those materials are actually used and released: the print shop. A newspaper is produced there, but it isn’t the source of the toxins itself; a library isn’t connected to industrial chemical production; a warehouse could store chemicals but wouldn’t explain toxins with a signature matching printing processes. So the evidence directly points to the print shop.
