1
00:00:01,860 --> 00:00:02,210
Okay.

2
00:00:02,520 --> 00:00:08,040
And this next video, we're going to be looking at a heading question.

3
00:00:08,430 --> 00:00:15,750
And the purpose of being doing this video is just to show you how you have to be able to drag and drop

4
00:00:16,020 --> 00:00:21,780
answer choices, how you have to be able to drag and drop answer choices.

5
00:00:22,390 --> 00:00:33,030
So in terms of strategy for a Headings question, I've given you a lot of lectures in the academic section.

6
00:00:33,030 --> 00:00:39,150
I've talked about it in the live class videos, I've talked about it in terms of strategy for the headings.

7
00:00:39,150 --> 00:00:46,590
Question I've gone over this a lot, so there have been a lot of videos that I put in there that have

8
00:00:46,590 --> 00:00:50,220
explained and talked about how to do a headings question.

9
00:00:51,870 --> 00:00:57,300
So with this one, again, the focus is not really about teaching strategy.

10
00:00:57,300 --> 00:01:06,210
I'm going to talk about strategy, but if you really want a lot of in-depth discussion and explanation

11
00:01:06,210 --> 00:01:12,780
of headings, question strategy, go look at the live videos, the live class videos, the covered it,

12
00:01:12,990 --> 00:01:19,080
and also the lectures in the general section and in the academic section that cover that topic.

13
00:01:21,090 --> 00:01:27,570
Now with the hanging headings question, you know, first of all, in terms of dragging and dropping,

14
00:01:28,050 --> 00:01:33,600
if this were the answer choice for number one, we will pull it over there in the box, drop it in there.

15
00:01:35,760 --> 00:01:40,160
And if I don't like that answer, I drag it over here and I drop it here.

16
00:01:40,350 --> 00:01:44,370
Here's number one, which covers these first two paragraphs.

17
00:01:47,160 --> 00:01:54,450
Number two is for this paragraph is for the paragraph that's below the number.

18
00:01:55,860 --> 00:01:58,320
Number three is for the paragraph below.

19
00:01:58,320 --> 00:02:02,730
The number number four is for the paragraph below the number.

20
00:02:07,470 --> 00:02:14,970
So with the head in question, you know, you know, my you know, my strategy already because you've

21
00:02:14,970 --> 00:02:17,700
been taking my course and you know my strategy already.

22
00:02:19,020 --> 00:02:26,730
My strategy focuses on looking at the first two sentences of a paragraph and then finding the information

23
00:02:26,730 --> 00:02:29,250
that matches what's in those first two sentences.

24
00:02:30,110 --> 00:02:37,760
The first two sentences are the most important sentences because they relate directly to the topic sentence,

25
00:02:37,760 --> 00:02:39,950
what the paragraph is all about.

26
00:02:42,230 --> 00:02:45,200
So for this one, I have to look at both of these paragraphs.

27
00:02:48,670 --> 00:02:56,260
Some years ago when several theoretical physicists, principally Heiberg and Kerner of Stuttgart, Germany,

28
00:02:56,920 --> 00:03:01,990
began publishing papers on traffic flow and publications normally rabbi traffic engineers.

29
00:03:02,440 --> 00:03:08,320
So these two physicists started to publish papers on traffic flow.

30
00:03:09,700 --> 00:03:14,560
They were clearly working outside their usual sphere of investigation.

31
00:03:15,250 --> 00:03:21,130
They had noticed that if they simulated the movements of vehicles on a highway using the equations that

32
00:03:21,130 --> 00:03:26,050
describe how the molecules of a gas move, some very strange results emerged.

33
00:03:27,190 --> 00:03:32,110
The strangest thing that came out of these equations, however, was the implication that congestion

34
00:03:32,110 --> 00:03:34,630
can arise completely, spontaneously.

35
00:03:34,990 --> 00:03:38,230
No external gas, no external causes are necessary.

36
00:03:38,980 --> 00:03:45,820
So when you look at these first, the first twos, the first sentences in these paragraphs and this

37
00:03:45,820 --> 00:03:48,700
top paragraph is telling us that these two physicists.

38
00:03:49,660 --> 00:03:56,860
Started publishing papers on traffic flow, which is usually done by traffic engineers.

39
00:03:57,580 --> 00:03:58,210
Right.

40
00:03:58,510 --> 00:04:01,600
And they had noticed something strange with their equations.

41
00:04:02,320 --> 00:04:04,780
So what matches that information?

42
00:04:06,610 --> 00:04:06,890
Right.

43
00:04:06,910 --> 00:04:08,650
What matches that information?

44
00:04:11,490 --> 00:04:12,960
See the answer already.

45
00:04:15,190 --> 00:04:20,320
Right how a concept from one field of study was applied to another, because the first sentence tells

46
00:04:20,320 --> 00:04:23,050
us what they were physicists.

47
00:04:23,350 --> 00:04:30,580
They applied their physicist knowledge to the to the area of traffic, engineering and traffic flow.

48
00:04:31,210 --> 00:04:40,000
So how one concept from one field physics was used and applied to another field traffic engineering.

49
00:04:40,300 --> 00:04:45,100
We pulled that directly from those first two sentences.

50
00:05:00,410 --> 00:05:02,480
Now we move down to the second one.

51
00:05:05,830 --> 00:05:11,890
The physicists if we wanted to, we can highlight it, which might be helpful.

52
00:05:16,420 --> 00:05:17,980
In terms of saying it better.

53
00:05:35,000 --> 00:05:35,270
Right.

54
00:05:35,340 --> 00:05:38,000
So when you're looking at that, you can see it a lot better, right?

55
00:05:40,920 --> 00:05:48,990
The physicists have challenged proposals to set a maximum capacity for vehicles on highways.

56
00:05:50,380 --> 00:05:56,140
They argue that it may not simply be enough to limit the rate at which the vehicles are allowed to enter.

57
00:05:56,710 --> 00:06:03,640
Rather, it may be necessary to tie these vehicles entry onto a highway precisely to coincide with a

58
00:06:03,640 --> 00:06:07,780
temporary drop in the density of vehicles along the road.

59
00:06:08,890 --> 00:06:10,840
So what does this sentence saying?

60
00:06:11,780 --> 00:06:12,060
Right.

61
00:06:12,110 --> 00:06:17,870
What does it saying is saying they're challenging these proposals to set a maximum capacity.

62
00:06:17,870 --> 00:06:26,150
They're challenging a proposal they're saying is not enough just to limit how many vehicles are allowed.

63
00:06:26,570 --> 00:06:27,680
It says you need to.

64
00:06:27,680 --> 00:06:30,140
You need to you need to regulate the time.

65
00:06:31,400 --> 00:06:31,820
Right?

66
00:06:31,820 --> 00:06:33,350
You need to regulate the time.

67
00:06:34,290 --> 00:06:35,100
So.

68
00:06:35,760 --> 00:06:37,800
What matches that information?

69
00:06:38,310 --> 00:06:39,470
A math experiment?

70
00:06:39,480 --> 00:06:40,800
Nothing about that.

71
00:06:41,370 --> 00:06:42,590
A lack of investment.

72
00:06:42,600 --> 00:06:45,360
No disagreement between experts?

73
00:06:45,390 --> 00:06:46,890
No, there are no disagreement.

74
00:06:47,250 --> 00:06:51,930
How different countries know the impact of driver behavior on traffic speed?

75
00:06:52,470 --> 00:06:53,160
No.

76
00:06:54,900 --> 00:06:55,500
Right.

77
00:06:55,710 --> 00:06:58,110
A proposal to take control away from the driver.

78
00:06:58,140 --> 00:06:59,550
That's our answer choice.

79
00:07:01,830 --> 00:07:03,690
Why is that our answer choice?

80
00:07:04,410 --> 00:07:10,140
Because it says it's not enough to simply say how many cars can go.

81
00:07:10,620 --> 00:07:16,500
What they're saying is you have to let the you have to only let the people you take it.

82
00:07:16,680 --> 00:07:18,690
You take the control away from the driver.

83
00:07:19,260 --> 00:07:21,540
The driver can no longer go when he wants to go.

84
00:07:22,110 --> 00:07:27,870
You tell him he can go enter at this time, at this rate.

85
00:07:31,440 --> 00:07:37,680
However, research into traffic control is generally centered in civil engineering departments, and

86
00:07:37,680 --> 00:07:41,520
here the theories of the physicist have been greeted with some skepticism.

87
00:07:41,520 --> 00:07:43,140
So we know what this is going to be about.

88
00:07:44,580 --> 00:07:46,200
We know this is going to be about.

89
00:07:47,400 --> 00:07:51,570
Look, the engineering people disagree with the physicists.

90
00:07:54,670 --> 00:07:58,750
Right here we're getting with areas of doubt.

91
00:08:02,480 --> 00:08:07,550
James Banke, a professor of civil engineering, civil and environmental engineering.

92
00:08:09,830 --> 00:08:15,470
Suggested that a sudden slowdown in traffic may have less to do with the chaos theory than with driver's

93
00:08:15,470 --> 00:08:16,520
psychology.

94
00:08:19,030 --> 00:08:19,630
Right.

95
00:08:20,110 --> 00:08:20,530
We're dealing with.

96
00:08:20,890 --> 00:08:26,650
So he's he's talking about in this first sentence, I can already look at it and tell you from this

97
00:08:26,650 --> 00:08:32,920
first sentence, I can look at it and tell you that this person is going to be talking about the driver's

98
00:08:32,920 --> 00:08:34,000
psychology.

99
00:08:35,140 --> 00:08:37,480
What is the driver thinking about?

100
00:08:38,600 --> 00:08:39,200
Okay.

101
00:08:39,560 --> 00:08:41,360
Look at your answer choices.

102
00:08:41,840 --> 00:08:44,270
There's only one answer choice.

103
00:08:44,270 --> 00:08:49,580
This talking about the driver's psychology or the driver's behavior.

104
00:08:49,940 --> 00:08:50,390
Right.

105
00:08:50,390 --> 00:08:52,430
The answer choice has to be this.

106
00:08:59,330 --> 00:09:00,830
So you see what happened there.

107
00:09:01,010 --> 00:09:05,120
If I don't put it all the way in the box, you'll reverse back.

108
00:09:06,050 --> 00:09:07,820
So you need to be careful.

109
00:09:08,270 --> 00:09:08,660
Right.

110
00:09:08,660 --> 00:09:09,740
That's not close enough.

111
00:09:09,950 --> 00:09:11,270
Both goes back.

112
00:09:11,780 --> 00:09:16,100
So you have to take that answer and put it all the way in the box.

113
00:09:16,610 --> 00:09:17,660
And they will stay.

114
00:09:18,910 --> 00:09:19,480
Okay.

115
00:09:19,660 --> 00:09:22,900
So that's how we do a matching headings question.

116
00:09:23,260 --> 00:09:28,450
And I kind of went over just strategy a little bit, a little bit more for you, but that's how you

117
00:09:28,450 --> 00:09:32,050
drag and drop, that's how you highlight the relevant sentences.

118
00:09:32,440 --> 00:09:36,700
But to really do well at this question, you have to be able to pull out.

119
00:09:36,700 --> 00:09:38,920
What is this question talking about?

120
00:09:38,920 --> 00:09:40,540
What are these sentences talking about?

121
00:09:40,540 --> 00:09:43,000
What's the controlling idea or controlling thought?

122
00:09:44,170 --> 00:09:44,860
Thanks a lot.
