A couple of math teacher colleagues of mine are discussing two interpretations of the following sentence:
A number will give the answer 6 when it has been doubled.
The intended interpretation was that "it" refers to "a number" (so that the required number is 3). The alternative interpretation is that "it" also could refer to "6" (so that the number is 12).
To me the sentence structure seems lacking for other reasons (how can a number "give an answer" at all), but I would appreciate your input on whether or not the second interpretation could be considered correct, as this is the way several students seem to have understood it.
