Foods are best stored dry because moisture

  • A.increases the weight and cost of transport
  • B.changes the colour of the finished product
  • C.allows microorganisms to grow
  • D.reacts chemically with most packaging materials

Answer: C

Correct answer: allows microorganisms to grow

It is available water that governs microbial growth, and drying is one of the oldest preservation methods for exactly that reason. Moisture also promotes chemical deterioration and insect activity, but the microbiological risk is the primary one and the reason dry goods are kept in sealed containers.
