1)
A ten-year comparison between the United States and the Soviet Union in terms of crop yields per acre revealed that when only planted acreage is compared, Soviet yields were equal to 68 percent of United States yields.
Here, we are focusing on the crop yielded PER acre. However, it is crucial to keep in mind that we are comparing ONLY the planted land
For instance, US cultivate 1000 acreage and from these, it yields 100 kg of brocccoli.
Russia of the same extension has 6.8 kg of broccoli
2)
When
total agricultural acreage (
planted acreage plus fallow acreage) is compared, however, Soviet yield was 114 percent of United States yield.
From the information above, which of the following can be most reliably inferred about United States and Soviet agriculture during the ten-year period?
A A higher percentage of total agricultural acreage was fallow in the United States than in the Soviet Union.
This is the correct choice. From what I have highlighted above is the only thing we can infer. For russia to have 114% means that the acreage it cultivates is almost if not in its entirety exploited
B The United States had more fallow acreage than planted acreage.
This is information is only partial if any
C Fewer total acres of available agricultural land were fallow in the Soviet Union than in the United States.
The total acres area can not be inferred because we do not have enough information
D The Soviet Union had more planted acreage than fallow acreage.
We do have only information about % not quantities of planted land
E The Soviet Union produced a greater
volume of crops than the United States produced.
The volume is out of scope
Hopèe now is more clear than before to you
