Boundary Value: Understanding the phrasing of the question

[qweiping31415]

I want to clarify what the question is trying to ask. I initially interpreted it as X is more effective, not more efficient than Y. In this case, I think it's both effective and efficient as compared to Y because the rate of finding defects per test case is higher for X. Not sure if I'm interpreting the question wrong or understanding the definition of efficiency wrongly.

In the actual exam, the notation: [x | y | z] will be used and no questions are entertained, with no underline as not. If the question was instead put into the examination's format, will the answer for this original quiz question and "X is [more effective "underlined", more efficient] than Y" have the same answer?

In the textbook, it was stated that

Efficiency: Fewer Test Cases to Find Same Number of Bugs
Effectiveness: More Bugs found with Same Number of Test Cases

Given X uses the same number of Test Cases to Find More Bugs, it will be termed as X being more effective!

For your question in the 2nd paragraph, it should have the same answer o.o

I can see how this question can cause some confusion due to the phrase (not efficient). It's not a good question. My fault. Just ignore that phrase.
