Reading Comprehension Question from Manhattan Test

For many years, home prices increased modestly, but in the past few years the price increases have begun to accelerate. If interest rates remain at their current high levels, many people who currently rent their residences will hesitate to purchase homes. As the price of real estate continues to climb, the costs of a mortgage will be too burdensome for these potential buyers. Fewer potential buyers will qualify for a mortgage. Sellers will be forced to lower their asking prices in order to compete for fewer and fewer buyers. So, high interest rates will eventually cause the real estate market to stabilize.

Select, by clicking on the passage itself, the sentence that most directly supports the author’s prediction about people who currently rent their residences.

The correct answer is shown as “As the price of real estate continues to climb, the costs of a mortgage will be too burdensome for these potential buyers. Fewer potential buyers will qualify for a mortgage.”

But the sentence before that also makes a direct prediction for people who currently rent their residences “If interest rates remain at their current high levels, many people who currently rent their residences will hesitate to purchase homes.” Why is this not the correct answer?

The question asks for “the sentence that most directly supports the author’s prediction”

The sentence you’re referring to “If interest rates remain at their current high levels, many people who currently rent their residences will hesitate to purchase homes” is the prediction itself

The sentence " As the price of real estate continues to climb, the costs of a mortgage will be too burdensome for these potential buyers. Fewer potential buyers will qualify for a mortgage"
supports the prediction
