Passage Map:
p1: Discusses how few people know about engineering
p2: Provides an example of an likely unknown fact of engineering
P3: Elaborates further from P2 and point out good qualities
P4: To conclude on the importance of engineering
Purpose(tone): discussion/ +ve
Question 1
A - No. We are discussing engineering as a whole, not the contributions to mankind
B - Author doesn't analyse 'why' people know little about engineering
C - only 1 example is given. The purpose of the whole passage isn't to evaluate good and bad.
D - No. The laymen is used as a data point for general awareness of engineering as compared with other professions, but we never explain how engineering is different.
E is correct because overall the author discusses the importance of engineering and provides examples of some of its feats. The "unique aspect" component surely throws people off, but this is the most correct.
Question 2
A - Correct. Stated in the first para "very little is known about (engineering) among those outside (engineering). Layment know something about law..."
B - We can't support this. Thus, it is incorrect.
C - I don't know about "considerable" knowledge. We are told that layment know "a little about medicine" in P1, but that's it. Eliminate
D - P3 contradicts this by stating that they did. Eliminate
E - We don't know this. It's way out of scope. Eliminate
Question 3 --Pre-think this as much from memory as possible. The author gives the example of two classes of engineers when he is trying to point out that laymen don't know anything about engineering.
A - Way to vague. The author literally only talks about 1 possible use in this example.
B - He states that one is an operator, but that isn't the point of his example in the actual passage itself. The point is to support that, overall, laymen don't know much about engineering
C - No. Same reason as B.
D - Yes. Matches up with our memory. This is What this example is trying to achieve in the passage as a WHOLE. We need to ask WHY the author put it here.
E - No. Not even supported.
