Question

High-yielding crops were plants specifically bred to respond to fertilizers; without fertilizers, they could not grow. For example, high-yield wheat varieties produced more grain per acre than traditional wheat plants. The seeds of high-yielding crops were larger, able to photosynthesize more efficiently, and able to grow even in places with limited sunlight. In addition, high-yielding crops meant that large varieties of crops were no longer necessary. Prior to the green revolution, thousands of varieties of a particular crop were being grown. Pesticides were used to prevent disease and pests that may harm high-yielding crops.

What is the benefit of high-yield crops?

Crops are larger and able to produce more grain per acre.
They increase the variety of crops needed to be produced.
They do not require the use of fertilizer.
They reduce the plant’s need to photosynthesize.

Answer 1

Crops are larger and able to produce more grain per acre.

Explanation: High-yielding varieties were bred to produce more grain per acre (and to photosynthesize more efficiently). They actually reduced the number of varieties grown, required fertilizers to perform well, and did not reduce photosynthesis needs.
