Hi Rich,

Thank you so much for taking the time to answer to my question.

I completely agree with you on the process to solve this IR tricky questions. However, what actually happened to me with this question was that I solved this problem with this "question-based approach", but when I finished my practice set and then came back to check my answers, even then I was still overwhelmed with the problem!

That´s what I wanted to check with the forum that I have correctly understood the graph.

To conclude, can we say that there are 16 different groups in the graph (4 subgroups of 4) and that we cannot possibly know which is bigger/smaller?

Thanks!

Hi minwoswoh,

I agree that there's no way to know how many people were polled in each "group"; there's also nothing to imply that the groups were all the same size.

From the first sentence of the text (next to the chart), it's not perfectly clear whether there are 16 groups or the same 4 groups polled 4 times. From the language, I actually think that it's the latter option though. Here's why:

1) The phrase "...subjects were asked about their LEVELS of exposure...at various TIMES during the election." The words "levels" and "times" implies that the subjects were polled about MORE THAN ONE point in time.
2) The phrase "...and whether they considered changing their votes....at ANY TIME during the election..." The words "any time" also imply MORE THAN ONE point in time. That question makes no sense if you're only asking a group about their opinions at just one point in time.

Notice how it doesn't really matter whether you think it's 16 groups or 4 groups though - the answer to the question doesn't change. In that way, GMAT prompts are always carefully worded - the Test results wouldn't be useful if the questions were debatable or open to interpretive 'bias.'

GMAT assassins aren't born, they're made,

Hi Rich,

Thanks again. You are indeed correct. It makes more sense that there are a total of 4 groups and each was polled 4 times.

With that reasoning, we can make such statements as "before the campaign, the more exposure people receive to television campaign news coverage, the less they consider changing their vote. On the other hand, near or on election day, the more exposure people receive, the more likely they are to consider changing their vote"

Tricky and interesting graph, indeed...

Thank you so much for your help, Rich.

Hi minwoswoh,

Your deductions in your last post are exactly what you're supposed to "see" in these graphs. Those are 2 "big picture" deductions and the IR section tends to reward Test Takers who can see those patterns.

Notice how the skills you used to make those deductions are rooted more in "CR skills" than in "math skills" - that's an important aspect of IR that a lot of people miss. The IR section is more about connecting ideas and spotting logical patterns than about high-level math skills.

Why is it not subject with 'low' exposure to tv news and 'early in campaign'? I reached the same answer as the official, but now I am second guessing myself and can not seem to come to an agreement with myself. I see the horizontal lines and think- its the same level of people considering changing votes.
Does the negative slope have an impact here? is that why this is not the answer?

Hi deeuk,

While that 'combination' (low level of exposure/early in the campaign) certainly shows a high chance of 'vote changing', it looks a little "lower" in the table than the correct answer (high level of exposure/on-near election day). In real basic terms, the "highest point" is the correct answer.

Official Explanation

RO1

The statement means to identify the participants that were most likely to consider changing their vote. According to the graphic, greater than 60% of participants in two groups considered changing their votes: those with a level 1 exposure early in the campaign, and those with a level 4 exposure on or near election day. Given that low exposure is not one of the options for the first blank, there must be a slightly greater percentage of the high-exposure group (level 4) who considered changing their vote.

The correct answer is high.

RO2

According to the graphic's key, the symbol for the high-level exposure group with the greatest percentage of participants who considered changing their vote corresponds to campaign news exposure on or near election day.

The correct answer is on or near election day.

I didn't see this question in GMAT prep focus exams 1 and 2. Maybe someone incorrectly added the tag, or maybe this came from focus exams 3-6, I don't know. Please share your thoughts.

PS: I see this question in GMAT Prep classic and EA exam.

Hi Sajjad1994,

I see that both those with a level 1 exposure early in the campaign and those with a level 4 exposure on or near election day have the same level on Y axis. How can you decide?
Both choices are in the option.
