According to a recent report, the original tires supplied with the Impressivo, a new sedan-class automobile, wore much more quickly than tires conventionally wear. The report suggested two possible causes: (1) defects in the tires, and (2) improper wheel alignment of the automobile.
Which of the following would best help the authors of the report determine which of the two causes identified was responsible for the extra wear?
(A) a study in which the rate of tire wear in the Impressivo is compared to the rate of tire wear in all automobiles in the same class
(B) a study in which a second set of tires, manufactured by a different company than the one that made the first set, is installed on all Impressivos and the rate of wear is measured
(C) a study in which the level of satisfaction of workers in the Impressivo manufacturing plant is measured and compared to that of workers at other automobile manufacturing plants
(D) a study that determines how often improper wheel alignment results in major problems for manufacturers of other automobiles in the Impressivo’s class
(E) a study that determines the degree to which faulty driving techniques employed by Impressivo drivers contributed to tire wear

A recent report, mentioned that original tyres supplied to Impressivo, a new sedan-class automobile, wore much more quickly than tires conventionally wear. The report suggested two possible causes: (1) defects in the tires, and (2) improper wheel alignment of the automobile.
We need to help the author to narrow down between the two options.
(A) a study in which the rate of tire wear in the Impressivo is compared to the rate of tire wear in all automobiles in the same class
The possible causes : Defects in tires and improper wheel alignment are both based on the particular vehicle- Sedan class Impressivo. This option compares two vehicles of the same class, this doesn’t mean the vehicles used the same type of tires manufactured by company A. OR both had same nature of Improper wheel alignment of the automobile. Hence, wrong.
(B) a study in which a second set of tires, manufactured by a different company than the one that made the first set, is installed on all Impressivos and the rate of wear is measured.
When a different set of tires from a different manufacturer is used in the Impressivo vehicle to test the tyre wear and tear compared to the first set. The result, helps us narrow down to the reasonable cause. If the outcome is no tyre wear - then the tires of the first set are defective, if the outcome is a tyre wear - then we can presume that wheel alignment can be an issue. Hence, correct.
(C) a study in which the level of satisfaction of workers in the Impressivo manufacturing plant is measured and compared to that of workers at other automobile manufacturing plants.
The level of satisfaction of the workers is not a criteria to determine the cause of reasons for the defects. Hence, wrong.
(D) a study that determines how often improper wheel alignment results in major problems for manufacturers of other automobiles in the Impressivo’s class
Does all other automobiles in the Impressivo class have the same wheel size and diameters. The study outcomes can be either way - supporting or opposing the improper wheel alignments. Without anything conclusive , the option is wrong.
(E) a study that determines the degree to which faulty driving techniques employed by Impressivo drivers contributed to tire
wear.
Option E is wrong, because it goes out of box to analyse the faulty driving techniques employed by Impressivo drivers eventually leading to tyre wear. This option speaks about the cause rather than the effect which needs to be studied.
Option B

OFFICIAL EXPLANATION
According to a recent report, the original tires supplied with the Impressivo, a new sedan-class automobile, wore much more quickly than tires conventionally wear. The report suggested two possible causes: (1) defects in the tires, and (2) improper wheel alignment of the automobile.
Which of the following would best help the authors of the report determine which of the two causes identified was responsible for the extra wear?
(A) a study in which the rate of tire wear in the Impressivo is compared to the rate of tire wear in all automobiles in the same class
(B) a study in which a second set of tires, manufactured by a different company than the one that made the first set, is installed on all Impressivos and the rate of wear is measured
(C) a study in which the level of satisfaction of workers in the Impressivo manufacturing plant is measured and compared to that of workers at other automobile manufacturing plants
(D) a study that determines how often improper wheel alignment results in major problems for manufacturers of other automobiles in the Impressivo’s class
(E) a study that determines the degree to which faulty driving techniques employed by Impressivo drivers contributed to tire wear
B
Because the report identifies two possible causes of the tire wear, the best answer must identify a study that focuses on one of these possible causes. Studies focusing on car models other than the Impressivo (A and D), worker satisfaction C, or driver error E are all irrelevant to this study. The study described in B removes one of the two possible causes. If the newly installed tires made by another manufacturer also turn out to wear abnormally, then the authors will have good reason to suspect that faulty alignment caused the initial problem. If the new tires wear normally, then they will know that the original tires were faulty.
