Question

During the early 20th century, in what way was the radio better than the phonograph in encouraging the concept of crosspollination?
Select one:
a. Phonographs were mostly owned by the wealthy
b. There were not enough records available
c. Phonographs were inferior in sound quality

Answer 1

C. Phonograph were inferior in sound quality.

Step-by-step explanation:

Researches have shown that plants respond to the sounds of their pollinator.

Some plants begin to produce a greater amount of nectar and some begin to vibrate to attract the attention of the pollinators towards them.

Greater the intensity of the sound of the pollinator, the faster the reaction will be.

Phonographs have a sound of lower intensity when compared to the intensity of sound produced by the radio.

Thus the radio was better than the phonograph in encouraging the concept of cross-pollination.
