COO of Codal: The code-quality assurance team has reported fewer number of errors per every thousand lines of code delivered by project Gutenberg's team so far this year than in any of the previous years. Definitely the recent process-quality initiatives taken by our company have started to pay off.

Vice President of Codal: The recent decision taken by Project Gutenberg’s manager to utilize old code, i.e., previously utilized code, is more likely the reason for the reduction in the number of errors

Which of the following, if true, most seriously calls the Vice President's hypothesis into question?

A. Many teams in the company have recently started adopting the reuse policy and are yet to report the benefits.
B. The team members of Project Gutenberg are no more likely than other teams in the company to utilize old code in the current projects.
C. The teams at Codal that did not utilize old code reported a significantly higher reduction in the average number of errors in their code.
D. The average number of errors per thousand lines of code delivered has been reducing for the past 3 years.
E. The Project Manager has not taken into account the data provided by other teams in the company.

COO of Codal: The code-quality assurance team has reported fewer number of errors per every thousand lines of code delivered by project Gutenberg's team so far this year than in any of the previous years. Definitely the recent process-quality initiatives taken by our company have started to pay off. (COO's conclusion in blue)

Vice President of Codal: The recent decision taken by Project Gutenberg’s manager to utilize old code, i.e., previously utilized code, is more likely the reason for the reduction in the number of errors. (VP's conclusion in blue)

Which of the following, if true, most seriously calls the Vice President's hypothesis into question?

A. Many teams in the company have recently started adopting the reuse policy and are yet to report the benefits.
B. The team members of Project Gutenberg are no more likely than other teams in the company to utilize old code in the current projects.
C. The teams at Codal that did not utilize old code reported a significantly higher reduction in the average number of errors in their code.
D. The average number of errors per thousand lines of code delivered has been reducing for the past 3 years.
E. The Project Manager has not taken into account the data provided by other teams in the company.

Pre-thinking: We need to find an answer to weaken VP's conclusion, an answer that may support COO's conclusion. What if the old code had many errors and the team managed to reduce it by using the qualities described by COO? In that case the VP's conclusion will fall apart. Lets analyze the answer choices.

A. This doesn't help to either weaken or strengthen VP's conclusion as no reporting has been made. Incorrect

B. The likelihood of utilizing the old code doesn't help to answer old codes' benefits. Incorrect

C. Interesting! this choice matches with our pre-thinking that the teams were able to reduce the errors by using the qualities stated by COO and since Project Gutenberg team utilized the old code, which apparently had many errors, was unable to reduce errors as much as other teams at Codal did. Hence, this is the the correct choice.

D. No comparison offered in this choice too for the two methodologies. Incorrect

E. Tricky! Although this option says that data from other teams has not been taken into account, we still don't know that whether other teams reported reduction in errors. So, eliminate E.

tarunanandani VP of Codal states that Project Gutenberg’s team has delivered better code by utilizing old code.
C) says that other teams got better results without using the old code.
In which way C) somehow questions the fact that the results delivered by Project Gutenberg’s team were due to old code? I mean, it only states that other solutions are more effective.
Where am I wrong?

Hi artiom01,
Lets see the argument again: The code-quality assurance team has reported fewer number of errors per every thousand lines of code delivered by project Gutenberg's team so far this year than in any of the previous years.
Now VP of Codal says that the above observation is because Project manager took the decision to use old code rather than company adopting process-quality initiatives.

The option C: The teams at Codal that did not utilize old code reported a significantly higher reduction in the average number of errors in their code.

Notice that the other teams achieved 'significant' reduction in the avg. number of errors. Now, the only difference, assuming other factors remaining same, as per the passage between other teams and the Project Gutenberg team is that other teams didn't use the old code. So, one can infer that the 'old code' must be the factor for less reduction of errors in case of Project Gutenberg team and hence this options call into question the VP's hypothesis.

Hope this helps!

Which of the following, if true, most seriously calls the Vice President's hypothesis into question? (an option which weakens the VP's hypothesis )

A. Many teams in the company have recently started adopting the reuse policy and are yet to report the benefits. ( doesn't talk about the Project G )
B. The team members of Project Gutenberg are no more likely than other teams in the company to utilize old code in the current projects. (Talks about the Project G and say that they are not using old codes, and hence it is opposite of what the VP hypothesised and hence weakens it ) let me know if i am wrong here?
C. The teams at Codal that did not utilize old code reported a significantly higher reduction in the average number of errors in their code. (not related to VP's hypothesis about project G)
D. The average number of errors per thousand lines of code delivered has been reducing for the past 3 years. (no effect)
E. The Project Manager has not taken into account the data provided by other teams in the company. (no effect)

C.The teams at Codal that did not utilize old code reported a significantly higher reduction in the average number of errors in their code.

As far as I'm concerned this only means that other methods are more efficient but does not argue that also using the old code could bring, although minor, benefits; in fact, this minor benefits can also be the main cause of Project G. error reduction.
The crucial aspect is that they are talking only about Project G.'s team. I mean, it could be that among many methods introduced by the Project G.'s team, the old code might be the most efficient, despite bringing less reduction in errors than methods introduced by other teams.
I'm quite lost because following this reasoning I can't find any suitable answer.

B. The team members of Project Gutenberg are no more likely than other teams in the company to utilize old code in the current projects.

Actually, it does not necessarily mean that the team does not use the old code. It could just be that all the teams of the company use the old code equally. (maybe I'm wrong)

In light of this passage and from the answer choices provided only option C seems to be the best among them. It may not be the ideal answer but by POE we can arrive at answer choice C.
As you mentioned option C points out that 'other methods are more efficient' and that what we need to weaken VP's conclusion. Remember VP's conclusion is that 'old code' is the reason for reduction in errors and not any 'other methods' (process-quality initiatives as proposed by COO). So, by saying that other methods might be more efficient we can call into question VP's conclusion.

shiva007
Option B states that Project G and other teams are both equally likely to use the old code. If anything this would strengthen VP's conclusion that 'old code' is the reason for the reduction in errors as all the teams are using it. Instead option C points out a difference in methodology adopted by Project G team and other teams and hence calls into question VP's conclusion.

Hope this helps!

Thank you for the clarification !
It’s just that I always get confused when “likely” is used in a complicated manner. Is there any post which can clarify on the usage of word “likely”?
