Im not sure if the OP posted the link but im going to try to do some cleaning up for the good people at PEW.

relevant questions seemingly are listed in the article as:
Who Achieves Eternal Life? - broken down into belief about one particular religion (the respondents), many possible solutions, or not certain
What determines Eternal Life? -belief, action, combination, dont believe in, or not certain
The responses are then displayed by this typical break down.
First main question:
Subset provided for individuals who chose many possible solutions (done by those who self-affiliated themselves with a particular religion) listing possible options (does this particular religion get you to heaven)
Also a question about how many religions can lead you to heaven (one, two, three, four, many) and the total proportion of those who cite at least one non-christian religion as a way to heaven (christians only)
Second main question:
responses are coded from the individuals response to an open ended question about how eternal life is achieved. Again the chart provided in the article is specifically related to christian responses. Included are belief, action, combination, and some others (the first three all have qualifications).
Also is a coding about how many christians believe their religion is exclusive (which i believe is gathered from previously responded to questions)
They also chart the changes in responses from their 2002, 2007, 2008 surveys by the subsets provided in the article (all which come from their general survey on religion)
In short i think its much better than its being given credit for, in what its trying to do (chart simple public opinion).
Also luns, i am looking for how they operationalized the belief in Jesus Christ. Currently im trying to use the 2007 general survey ( i cant find the full 2008 one yet, i dont think its out) but im only part way through the report.
