50. The word “disparate” in line 20 (paragraph 2) is closest in meaning to:
(A) contrasting
(B) homogeneous
(C) various
(D) separate

46. Which of the following may serve as the title for this passage? (A) Physiological condition does impact slant overestimation (B) The relationship between motor operation and slope climbing (C) The impact of slant steepness on visual misperception (D) A cognitive account for people’s overestimation of steepness

47. Which of the following statement is NOT true? (A) Our visual misperception is influenced by height. (B) Slant overestimates is not observed in the escalator group. (C) Physiological factors such as aging and fatigue do not seem to impact slant overestimates. (D) Decreased physiological potential due to fatigue and increasing age leads to further exaggerations of the steepness of hills.

48. Which of the following sentence can be added to the end of the last paragraph without disrupting the flow of the whole passage? (A) The above research finding thus provides convincing evidence that we are hardwired to be overly sensitive to changes in terrain slope. (B) A wealth of evidence has shown that people verbally overestimate the slant of hills by 15° to 20°. (C) Maybe people tend to overestimate the steepness of slopes and not because they are lazy. (D) Thus, the evidence favoring a psychological explanation has been disputed.

49. What does the author mean by “misperception of slope steepness only happened at the chance level” for participants assigned to the escalator group? (A) Misperception of slant is consistently observed. (B) The occurrence of misconception is not observed. (C) The slope steepness is estimated in a biased and unfair way. (D) The tendency to overestimate a slant cannot be consistently obtained.
