If the outside of the can were sampled, what would you expect?

Sampling the outside of a can would likely reveal that it is covered in microbes. This is due to the regular exposure of the can's surface to the environment, including various surfaces it may have come into contact with, handling by people, and the particles and microorganisms present in the air.

Microbes, including bacteria, fungi, and other microorganisms, are ubiquitous in the environment. They can easily adhere to surfaces, particularly those that are not sterile. The exterior of cans, frequently touched and transported, tends to accumulate these organisms.

While the inside of the can is typically designed to be sterile and sealed to preserve contents, the outside is subjected to many environmental factors that contribute to microbial growth or presence. Therefore, finding a significant microbial presence on the can's surface is expected, confirming the answer as accurate.
