Reading Answers
1 Answer: True
Question type: True/False/ Not Given Answer location: Paragraph A Answer explanation: In the introductory lines of paragraph A, it is mentioned that however much we may abhor it, deception comes naturally to all living things. Birds do it by feigning injury to lead hungry predators away from nesting young. Spider crabs do it by disguise: adorning themselves with strips of kelp and other debris, they pretend to be something they are not-and to escape their enemies. These lines indicate that despite regarding it with disgust, deception comes naturally to everyone (all living things), which explicitly implies that all living creatures including the animals and birds were included in it. Thus, the statement agrees with the information, so, the answer is True.
2 Answer: True
Question type: True/False/ Not Given Answer location: Paragraph A, last line Answer explanation: The last line of paragraph A states, “Psychologist Gerald Jellison of the University of South California, are lied to about 200 times a day, roughly one untruth every five minutes—often deceive for the same reasons: to save their skins or to get something they can’t get by other means.” We can understand from these lines that people lie to save themselves or to get something they can’t get by other means. Here, self-preservation refers to the act of protecting oneself from harm or death. Thus, it’s clear that some people tell lies for self-preservation, so, the answer is True.
3 Answer: False
Question type: True/False/ Not Given Answer location: Paragraph B Answer explanation: Paragraph B illustrates that knowing how to catch deceit can be just as important a survival skill as knowing how to tell a lie and get away with it. These lines indicate that lying is an important survival skill than any other offense, that is knowing how to catch deceit is as important as knowing how to tell a lie and get away with it. Thus, it’s clear that detecting a lie is not important. Hence, the statement contradicts the information, so, the answer is False.
4 Answer: Not Given
Question type: True/False/ Not Given Answer location: Paragraph E, line 2 Answer explanation: We find a reference for the brain in the 2nd line of paragraph E, which states that neurological studies even suggest that genuine emotions travel different pathways through the brain than insincere ones. These lines suggest that according to neurological studies, genuine emotions travel different pathways through the brain than insincere ones. Thus, there’s no reference to the fact that researchers are using equipment to study which part of the brain is responsible for telling lies. Hence, the answer is Not Given.
5 Answer: True
Question type: True/False/ Not Given Answer location: Paragraph C Answer explanation: The introductory lines of Paragraph C state that lies work best, successful liars need to accurately assess other people’s emotional states. These lines suggest that understanding emotions accurately will help a successful liar to influence someone. Thus, the statement agrees with the information, so, the answer is True.
6 Answer: D
Question type: Multiple Choice Question Answer location: Paragraph D Answer explanation: Paragraph D illustrates even high-tech lie detectors don’t detect lies as such; they merely detect the physical cues of emotions, which may or may not correspond to what the person being tested is saying. These lines suggest that high-tech lie detectors don’t detect lies such as that they detect the physical cues of emotions which may or may not respond to what the person being tested is explaining. Hence, it is evident that a lie detector works when it detects body behavior during one’s verbal response. Thus, the answer is C.
7 Answer: B
Question type: Multiple Choice Question Answer location: Paragraph D, line 9 Answer explanation: The 9th line of paragraph D states that on the other hand, it might also mean that the lights in the television studio are too hot-which is one reason polygraph tests are inadmissible in court. We can deduce from these lines that the studios were too hot so the polygraph test is inadmissible. Therefore, somebody’s behavior changes were observed due to the changes in the surroundings. Thus, lie detectors can’t be used as evidence in a court of law because they’re based on too many verbal and non-verbal clues. Hence, the answer is B.
8 Answer: A
Question type: Multiple Choice Question Answer location: Paragraph E, line 5 Answer explanation: The 5th line of paragraph E states that If a patient paralyzed by a stroke on one side of the face, for example, is asked to smile deliberately, only the mobile side of the mouth is raised. We can deduce from these lines that the author has taken paralyzed patients as an example to illustrate the relation between the true emotions which sometimes were absent in some paralyzed patients, which could affect the person, who is taken for a lie detection test. Therefore, the author has mentioned the paralyzed patients to exemplify people’s responses to true feelings. Thus, the answer is A.
9 Answer: B
Question type: Multiple Choice Question Answer location: Paragraph E, line 8 Answer explanation: The 8th line of paragraph E states that very few people-most notably, actors and politicians can consciously control all of their facial expressions. Lies can often be caught when the liar’s true feelings briefly leak through the mask of deception. We can understand from these lines that actors, politicians, and actors can consciously control their facial expressions, that is they try to mask their faces and heart so that they give false information/ statements and take us far away from reality. Thus, it is evident that according to paragraph E, politicians are good at masking their emotions. Hence, the answer is B.
10 Answer: C
Question type: Multiple Choice Question Answer location: Paragraph F, last line Answer explanation: The last line of paragraph F states that “If someone claims they are sad and the inner corners of their eyebrows don’t go up,” Ekman says, “the sadness is probably false. These lines suggest Ekman saying that if someone claims they’re sad and if the inner corners of their eyebrows don’t go up, their sadness is false. Thus, the answer is sadness.
11 Answer: A
Question type: Multiple Choice Question Answer location: Paragraph G, line 4 Answer explanation: The 4th line of Paragraph G states that a genuine smile affects not only the corners of the lips but also the orbicularis oculi, the muscle around the eye that produces the distinctive “crow’s-feet” associated with people who laugh a lot. A counterfeit grin can be unmasked if the lip comers go up, the eyes crinkle but the inner corners of the eyebrows are not lowered, a movement controlled by the orbicularis oculi that are difficult to fake. These lines indicate that the smile affects the corner of the lips and the muscle around the eye that produces the distinctive crow’s feet with people who laugh a lot, which means it is associated with happiness. Thus, the answer is A.
12 Answer: B
Question type: Multiple Choice Question Answer location: Paragraph F, line 3 Answer explanation: The 3rd line of paragraph F states that by contrast, the lowering of the eyebrows associated with an angry scowl can be replicated at will by almost everybody. We can deduce that the statement is in contrast which explains the lowering of eyebrows which usually occurs when someone scowls with anger or shortens the eyes to deny something. Thus, the lowering of eyebrows is associated with anger. Hence, the answer is B
13 Answer: C
Question type: Multiple Choice Question Answer location: Paragraph F Answer explanation: The introductory lines of paragraph F states that one of the most difficult facial expressions to fake—or conceal, if it is genuinely felt—is sadness. When someone is truly sad, the forehead wrinkles with grief, and the inner corners of the eyebrows are pulled up. These lines indicate that the difficult facial expressions are to fake or conceal if sadness is felt genuinely. The inner corner of the eyebrows is raised means that they happen when someone wrinkles their forehead in grief or sorrow such that the eyebrows are pulled up. Thus, the inner corner of the eyebrows is raised due to sadness. Hence, the answer is C.
