In each example you will read a short sentence (or two). Then, a pronoun in the text is mentioned. Your task is to choose a referent which the mentioned pronoun refers to. You will be given two options in each case and one choice should seem much more likely to you than the other.

Let me give you an example: sentence: i couldn't put the saucepan on the rack because it was too tall .pronoun: it. A) the saucepan B) the rack
The answer to this example can be: the saucepan
Here is why: If the saucepan couldn't be put on the rack, it was probably bigger in size than the rack, so the pronoun "tall" refers to the saucepan.

OK. solve this:
