I can't seem to escape the high 30s and I'm thinking it comes down to a certain understanding that just has not come to me. I'm hoping I can get someone who has scored in the mid to high 40s to look at this sentence correction question to describe what he is thinking on these questions so that I can divine some understanding for myself. When I make mistakes on CR, the passage and the answer choices long and convoluted which usually means that I don't know what is being said without reading several times. This is extremely time consuming but if I am at the high 30 level these are the questions I will continually be given. How do I better prepare for this?
Here is an example of this kind of CR question. When you look at this break down your thoughts. If you were being timed and after several of these how would you handle this? Did you understand what was being said in the stem after the first reading or the answer choices? How were you able to what determine the discrepancy that needed to be resolved? What method do you use to see the difference in the answer choices? Thanks in advance for your assistance.
The brightness of each pixel making up a Landsat satellite image corresponds to the average reflected light from 80 square meters of the earth's surface. Land which has been cleared reflect more light than rainforest. After counting the brighter pixels on Landsat images of the Amozonian and Congan rainforests, scientists concluded that both had suffered large scale deforestation. Ground observers confirmed that large areas of the Amazonian rainforest had been cleared, but the level of deforestation of the Congan rainforest had been greatly overestimated.
Which of the following, if true, forms the basis of an explanation of the accuracy of the estimations of deforestation in the Amazonian and Congan rainforests? (even the question is convoluted)
1) The Congan rainforest is completely covered by Landsat images, while the coverage of the Amazonian rainforest is incomplete.
2) Cleared spots in the Congan rainforest tend to be much smaller than those in the Amazonian rainforest, but appear to be the same size on Landsat images.
3)Land clearing in the Amazon is usually of old growth forest, while that in the Congo tends to be secondary growth rainforest that has previously been cleared and allowed to lie fallow for up to 20 years.
4) The people living in the rainforest in the Congo mainly rely on subsistence farming and so clear smaller plots of land than the larger commercially farmed areas of the Amazon.
5) Clouds often make it impossible to test Landsat images of the Congan rainforest, while the Amazonian rainforest is usually cloud-free.
