Google Inc. accused rival Microsoft Corp.’s Bing Search of copying its internet search results. To prove its claim, Google did a series of tests. As an example, in one of the tests, it changed its algorithm to show a link to the website for Blackberry maker Research In Motion Ltd if users searched for "mbzrxpgjys", a result that was essentially irrelevant. When this test was executed, the same result showed up on Bing. In fact, Google found such copying in nine out of 100 different search queries it tested.


If Google’s claim that Microsoft is copying it’s search results is true, what else must be true?

A. Users who typed "mbzrxpgjys" found the link to the website of Research In Motion Ltd. useful.

B. If two search engines return the same search results for 9 or more out of 100 search terms, then one search engine must be copying the other.

C. It is highly unlikely that the irrelevant results from two different search engines would match unless one copied the other.

D. The number of search queries for “mbzrxpgjys” did not increase tremendously in the time period when Google carried this test out.

E. Copying irrelevant results is as severe a crime as copying relevant search results.

When this test was executed, the same result showed up on Bing. In fact, Google found such copying in nine out of 100 different search queries it tested.

Analysis-
> G accused M for copying search results
>An irrelevant search was adopted by G to prove the copying by M
> Results match
> 9/100 cases show copying


If Google’s claim that Microsoft is copying it’s search results is true, what else must be true?

Question analysis- GIVEN- M copied G results. Also must be true?

Pay attention to the given data in question as it makes our belief in passage concrete.
This is an ALSO must be true.

A.
Users who typed "mbzrxpgjys" found the link to the website of Research In Motion Ltd. useful.
- WRONG- how the data was useful is out of scope

B.
If two search engines return the same search results for 9 or more out of 100 search terms, then one search engine must be copying the other.
- WRONG-cause and effect is not given. This is just in Google's case. This answer choice makes a general causal (if ...then.) statement which is too broad to be true.

C. It is highly unlikely that the irrelevant results from two different search engines would match unless one copied the other.- CORRECT- the question tells us that M copied G. So it is HIGHLY LIKELY THAT THE TEST RESULTS ARE INDICATIVE OF COPYING. Now the conclusion made in the question statement is based on the research done so the research data is conclusive enough to prove the conclusion . SO THIS MUST BE TRUE ,otherwise the conclusion in question statement may not hold.

D.
The number of search queries for “mbzrxpgjys” did not increase tremendously in the time period when Google carried this test out.
- WRONG-no relationship between no. Of results and time period- out of scope

E.
Copying irrelevant results is as severe a crime as copying relevant search results.
- WRONG-crime - OUT OF SCOPE

Can someone explain why B is wrong elaborately?

Hey sahanas,

Basically, answer choice (B) contains two things which make it incorrect:
- it describes an unspecified set of search terms (i.e. if you pick any 100 terms, 9 of them will be the same) as opposed to a specifically engineered set of 'irrelevant terms' described in the passage. For example, if the 100 terms were all highly popular words and 9 of the searches led to the same Wikipedia page, then Google likely wouldn't claimed Microsoft was copying their results...
- it contains the word "must". An extreme word like "must", "always", "never" in a GMAT answer is a red flag, as the logic is rarely 100%. In this case, the correct answer uses a weaker wording 'highly unlikely'.

Does this help?
