Question 16.
0:08
Taylor: Researchers at a local university claim that 61 percent of the information transferred
0:14
during a conversation is communicated through nonverbal signals.
0:18
But this claim, like all such mathematically imprecise claims, is suspect because claims
0:23
of such exactitude could never be established by science.
0:27
So pausing here looking at Taylor's passage first, argument or facts?
0:32
And clearly we have an argument.
0:34
Taylor's point is that this claim is suspect.
0:39
And what is this claim?
0:40
Well, the claim that researchers are making that 61 percent of information transferred
0:46
during a conversation is communicated through nonverbal signals.
0:51
And how do we know that this claim is suspect?
0:53
Well, the premise is that because claims of such exactitude could never be established
1:00
by science.
1:01
Okay, so now turning our attention to Sandra: While precision is unobtainable in many areas
1:07
of life, it is commonplace in others.
1:10
Many scientific disciplines obtain extremely precise results, which should not be doubted
1:16
merely because of their precision.
1:19
So Sandra, argument or facts?
1:22
You notice this is clearly just a set of facts here where she points out some considerations
1:27
that she believes that Taylor's overlooking?while precision is unattainable in many areas of
1:33
life, it's commonplace in others, and many scientific disciplines obtain extremely precise
1:38
results so they should not be doubted merely because of this precision.
1:43
All right, so moving to the questions stem, the statements above provide the most support
1:48
for holding that Sandra would disagree with Taylor about which one of the following statements.
1:55
Disagree.
1:57
So this is a Point at Issue question.
2:01
So a type of Must Be True question because again we're looking to the statements that
2:08
these individuals have made and trying to find the point that they disagree about.
2:14
So let's turn our attention here to (A).
2:18
Research might reveal that 61 percent of the information taken in during conversation is
2:24
communicated through nonverbal signals.
2:28
Is that the point at issue?
2:32
What will Taylor say to (A)?
2:37
We're not quite sure if research might reveal it, Taylor's just saying that we can't believe
2:43
this claim because claims of such exactitude could never be established by science.
2:49
So actually I guess Taylor would disagree with this.
2:51
He does not believe that research can reveal this because claims of such exactitude could
2:57
never be established by science.
2:59
So safe to say that Taylor disagrees.
3:01
But what about Sandra?
3:06
Do we know what Sandra thinks about (A)?
3:09
Does Sandra mention whether she believes research might reveal that 61 percent of the information
3:15
taken in during a conversation's communicated through nonverbal signals?
3:18
And you notice, she does not mention that.
3:20
Sandra's claims are much more broad, much more general, doesn't address (A) so we don't
3:28
know Sandra's opinion so (A) cannot be the correct answer and (A) would be eliminated.
3:35
Again, we're looking for an answer choice where somebody agrees and the other person
3:39
disagrees.
3:40
Which brings us to (B).
3:41
It is possible to determine whether 61 percent of the information taken in during a conversation
3:47
is communicated through nonverbal signals.
3:51
So kind of similar to (A).
3:54
Research might reveal, (B) says it is possible to determine but again, this is what Taylor
4:01
seems to be taking most issue with, this idea of being able to determine whether this claim
4:07
is accurate because again such claims of exactitude have never been established by science.
4:13
So again, seems like Taylor would disagree with that statement.
4:19
Does not agree that it's possible to determine whether this happens, because claims of such
4:24
exactitude could never be established by science.
4:27
What about Sandra though?
4:28
And again you notice same problem that we had in (A) we have in (B), Sandra does not
4:31
address this.
4:32
Sandra's claims are much more broad and general so we do not know Sandra's opinion on (B)
4:40
so (B) is out.
4:41
(C) the study of verbal and nonverbal communication is an area where one cannot expect great precision
4:49
in one's research results.
4:51
Well, do we know what Taylor thinks about (C)?
4:56
The study of verbal and nonverbal communication is an area where one cannot expect great precision
5:02
in one's research results.
5:04
And again you notice Taylor does not address (C) at all.
5:09
We do not know Taylor's opinion of that.
5:11
We just know that this claim that 61 percent of information is transferred during a conversation
5:17
nonverbally is suspect because claims of such exactitude could never be established by science.
5:26
Sandra too, we have no idea what Sandra's opinion on this is.
5:29
We know that Sandra thinks that many scientific disciplines obtain extremely precise results.
5:36
But nothing about the study of nonverbal or verbal communication.
5:40
So again, we do not know either's opinion on (C) so (C) clearly does not follow.
5:45
Moving to (D), some scientists can yield mathematically precise results that are not inherently suspect.
5:53
So let's take a look now, what does Taylor think about (D)?
5:57
If you look at Taylor's last sentence, his premise is, ". . . claims of such exactitude
6:04
could never be established by science."
6:08
So clearly Taylor disagrees that some sciences can yield mathematically precise results that
6:13
are not inherently suspect.
6:17
So Taylor clearly disagrees, but what about Sandra?
6:22
And you notice Sandra says, "Many scientific disciplines obtain extremely precise results
6:31
that should not be doubted merely because of their precision."
6:35
So Sandra agrees with (D).
6:39
So (D), Taylor would disagree with it, Sandra agrees with the statement.
6:46
That is their disagreement, it is the point at issue, so (D) would be the correct answer.
6:52
But again, just making sure, checking (E), if inherently suspect claims are usually false
7:00
then the majority of claims made by scientists are false as well.
7:06
So we see a general principle in (E) and clearly we know neither Taylor nor Sandra's opinion
7:13
on this general principle, they never address it so how could (E) be their disagreement.
7:18
(E) is eliminated.
