51. Choose the correct word to use in the blank: '________ of thinking does not allow a professor to consider another point of view.'
Answer: C
Rigidity of thinking does not allow a professor to consider another point of view.
The term "rigidity" accurately describes a lack of flexibility in thinking, highlighting an inability to entertain alternative perspectives.
A) Flexibility
Flexibility refers to the ability to adapt or change one's thoughts or approaches. This option contradicts the context of the sentence, as it suggests an openness to different viewpoints rather than a restriction in considering them.
B) Rigid
While "rigid" is a synonym for "rigidity," it is an adjective and does not fit grammatically in the blank, which requires a noun. Therefore, it does not serve as a suitable choice in this context.
C) Rigidity
Rigidity is the correct choice as it functions as a noun, effectively conveying the concept of inflexible thinking that prevents a professor from considering other viewpoints. This term encapsulates the intended meaning of the sentence.
D) Flexible
Flexible implies adaptability and openness, which is the opposite of what the sentence is aiming to convey. This option does not align with the idea of being unable to consider different perspectives.
Conclusion
The correct answer, "rigidity," encapsulates the central idea of inflexible thinking that inhibits the consideration of alternative viewpoints. All other options either do not fit grammatically or convey an opposing meaning, reinforcing the necessity of "rigidity" in this context.
