Question 85: Science and Technology

What is the Universal Product Code (UPC) adopted for?

aFire safety code in buildings
bEarthquake-resistant buildings code
cBar code
dAgainst adulteration eatables

AnswerThe answer is (c).

The Universal Product Code (UPC) is a bar code: a pattern of black bars and spaces that encodes a 12-digit number identifying a product, read by a scanner at the checkout. It has nothing to do with fire safety, earthquake-resistant building rules or the prevention of food adulteration.

Why each option is right or wrong
  • (a) Not a fire safety code.
  • (b) Not a building code for earthquakes.
  • (c) Correct: the UPC is a bar code.
  • (d) Not a code against food adulteration.
