question 73:
adding a floral ______ to the water is very effective in extending the life of fresh flowers.
a. 12
b. 16
c. preservative
d. respiration
e. transpiration

Explanation:

To solve this, we analyze the options. The sentence is about extending fresh flowers' life in water. A floral preservative is a substance used to prolong the life of cut flowers by providing nutrients, inhibiting bacteria, etc. "12" and "16" are numbers, not relevant. "Respiration" is a plant process, and "Transpiration" is water loss from plants, neither related to adding to water for flower life extension. So the correct option is the one related to a substance for flowers, which is "Preservative".

Answer:

C. Preservative
