Question 1

Between which two months was there the smallest proportional increase or decrease in the mileage of Surveyor 1 in comparison to the previous month?

Accepted Answer

Months 4 and 5

Answer

The correct answer is (D)
To determine the rate of increase or decrease between two months, use this formula: 
|Mileage in the current month - Mileage in previous month| / Mileage in the previous month

Between months 1 and 2: |3,256 ― 2,675| / 2,675 = 0.217 = 21.7%

Between months 2 and 3: |1,890 ― 3,256| / 3,256 = 0.419 = 41.9%

Between months 3 and 4: |3,892 ― 1,890| / 1,890 = 1.059 = 105.9%

Between months 4 and 5: |3,401 ― 3,892| / 3,892 = 0.126 = 12.6%

The answer is Months 4 and 5.

The final statement is not true.

Because Mr. Brown's rabbits are grey and all grey creatures are kind, we can deduce that Mr. Brown's rabbits are definitely kind.

Question 3

A dress was initially marked at $150, and a pair of jeans were priced at %50. If Emily got a 40% discount off the dress and a 20% discount on jeans, what was the total percentage she saved on her purchases?

Accepted Answer

35%

Answer

To find the percentage Emily saved, you need to divide the savings by the total pre-sale cost.

Saving on dress: $150 x 40% = $60

Saving on jeans: $50 x 20% = $10

Total savings: $60 + $10 = $70

Total pre-sale cost: $150 + $50 =$200

Total savings in percent: 70/200

Cancel both the numerator and denominator, by 2:

(70÷2)/(200÷2) = 35/100 = 35%

Question 4

Everyone who has been diagnosed with sleep apnoea has encountered a personal battle owing to the disease. For example, Vicki suffered from depression and lost her job, while Bill felt a strain on his marriage.

Proposed assumption: Vicki and Bill encountered a personal battle because they couldn't come to terms with their disease.

Accepted Answer

B. Conclusion does not follow

Answer

The correct answer is B (Conclusion does not follow).

It is plausible that the reason people who suffer from sleep apnoea encounter a personal battle is because of an inability to come to terms with this disease. However, since the passage does not provide an actual reason, you cannot reach this conclusion without reasonable doubt.
