Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
GM crops that produce a higher yield per plant than unmodified crops would
A
a. produce more food for the same acreage.
B
a. produce less food for the same acreage.
C
a. produce more food but would use more land.
D
produce less food and require more land.
Explanation: 

Detailed explanation-1: -The reduction of losses by pests, viruses and weeds that compete for soil nutrients, together with savings in phytosanitary products and fuel, indirectly increase the final yield when compared with conventional crops.

Detailed explanation-2: -On average, GM technology has increased crop yields by 21% (Figure 2). These yield increases are not due to higher genetic yield potential, but to more effective pest control and thus lower crop damage [27]. At the same time, GM crops have reduced pesticide quantity by 37% and pesticide cost by 39%.

Detailed explanation-3: -The researchers’ key findings: GMO corn varieties increased crop yields 5.6 to 24.5 percent relative to their non-GMO equivalents.

Detailed explanation-4: -The three most common traits found in GMO crops are: Resistance to certain damaging insects. Tolerance of certain herbicides used to control weeds. Resistance to certain plant viruses.
