Determine and prove whether an argument in English is valid or invalid. Prove whether each argument is valid or invalid. First find the form of the argument by defining predicates and expressing the hypotheses and the conclusion using the predicates. If the argument is valid, then use the rules of inference to prove that the form is valid. If the argument is invalid, give values for the predicates you defined for a small domain that demonstrate the argument is invalid. QUESTION A AND B ALREADY SOLVED. PLEASE solve part C, D, E using same method, and give some explantion for your answer. THANKS! The domain for each problem is the set of students in a class. (a) Every student on the honor roll received an A. No student who got a detention received an A. No student who got a detention is on the honor roll. H(x): x is on the honor roll A(x): x received an A. D(x): x got a detention.

Answers

Answer 1

Hello! I'm happy to help you out in this matter. Following is the answer to your argument :

(c) Every student who received an A is on the honor roll.
H(x): x is on the honor roll
A(x): x received an A.
This argument is invalid. We can show this by giving a counterexample. For example, consider a scenario where there is a student named John who received an A, but he is not on the honor roll. This scenario contradicts the conclusion of the argument, which states that every student who received an A is on the honor roll. Therefore, the argument is invalid.

(d) No student who is on the honor roll received a detention.
H(x): x is on the honor roll
D(x): x got a detention.
This argument is valid. We can prove its validity using the rules of inference. The argument can be written symbolically as ¬∃x(H(x) ∧ D(x)), which can be rewritten using De Morgan's law as ∀x(¬H(x) ∨ ¬D(x)). This is a valid argument form known as the rule of inference called universal instantiation.

(e) Every student who did not receive an A got a detention.
A(x): x received an A.
D(x): x got a detention.
This argument is invalid. We can show this by giving a counterexample. For example, consider a scenario where there is a student named Sarah who did not receive an A, but she did not get a detention either. This scenario contradicts the conclusion of the argument, which states that every student who did not receive an A got a detention. Therefore, the argument is invalid.

Read the excerpt from the passage. ". . . You could almost see that thought turn in him as he turned, and pace in him as he paced; so completely possessing him, indeed, that it all but seemed the inward mold of every outer movement. "


Which idea does the author convey through the use of figurative language?

Answers

The author uses figurative language to convey the idea that the character's thought is deeply ingrained and influential in his actions.

The idea that is conveyed

The phrase "you could almost see that thought turn in him as he turned" suggests a strong correlation between the character's mental process and his physical movements.

The use of the word "pace" further emphasizes the connection, as it implies a rhythmic and repetitive motion that mirrors the character's thought process.

By describing the thought as "the inward mold of every outer movement," the author suggests that it shapes and molds the character's behavior in a profound and pervasive manner. Overall, the figurative language portrays the character's thoughts as a powerful force that drives and directs his actions.

According to the information we can infer that the barrier implied in the situation is Cultural barrier (option A).

Which barriers in communication is being implied in the situation?

In the given situation, the barrier in communication that is being implied is a cultural barrier. Johan's preconceived notions and biases about how most Indians speak, based on the complaints he hears from his sister, create a cultural barrier.

Additionally, his sister's negative comments about Indians' speaking skills have shaped his perception and created a stereotype. This cultural barrier hinders Johan from actively listening and engaging in the meeting with the Indian staff member, leading him to only pretend to listen and rush the meeting.

According to the above, it highlights a lack of cultural understanding and sensitivity, which can impede effective communication and collaboration.
