421
If A→B, B→C, C→A, and exactly 2 are true, what follows?
Analytical Reasoning
A. All are true
B. All are false
C. Contradiction
D. One is true
Answer: The cycle A→B→C→A means if any one is true, all are true. Exactly 2 true is impossible.
422
What assumption supports? \'Gene editing will cure genetic diseases because CRISPR can target specific genes.\'
Analytical Reasoning
A. CRISPR can target genes
B. Genetic diseases have specific gene targets
C. Targeting genes cures diseases
D. All of the above
Answer: For the argument to hold, all these assumptions must be true.
423
A is older than B. C is younger than D. B is older than D. C is older than A. Who is oldest?
Analytical Reasoning
A. A
B. B
C. C
D. D
Answer: C>A, A>B, B>D, C>D, so C is oldest.
424
Which strengthens? \'CRISPR gene therapy cures sickle cell disease because it corrects the genetic mutation.\'
Analytical Reasoning
A. CRISPR can edit genes
B. Sickle cell is caused by a mutation
C. Correcting mutations cures diseases
D. All of the above
Answer: For the argument to hold, all these assumptions must be true.
425
A is married to B. C is B\'s sibling. D is C\'s child. E is D\'s spouse. What is A to E?
Analytical Reasoning
A. Parent
B. In-law
C. Sibling
D. Cousin
Answer: A is married to B, B is C\'s sibling, D is C\'s child, E is D\'s spouse. A is E\'s spouse\'s parent\'s sibling-in-law\'s spouse\'s... essentially in-law through marriage.
426
What is the flaw? \'If we regulate social media, free speech will die.\'
Analytical Reasoning
A. Slippery slope
B. Ad hominem
C. Straw man
D. Circular reasoning
Answer: Assuming regulation leads to the death of free speech is a slippery slope.
427
If exactly 5 of 7 statements are true, and they form a chain 1→2→3→4→5→6→7, what follows?
Analytical Reasoning
A. Statements 1-5 are true
B. Statements 3-7 are true
C. Cannot determine which 5
D. All statements are true
Answer: Without knowing which 5 are true, we cannot determine their positions in the chain.
428
A is the father of B. C is the daughter of B. D is the mother of C. What is the relationship between A and D?
Analytical Reasoning
A. Father and daughter
B. Father-in-law and daughter-in-law
C. Brother and sister
D. Grandfather and grandmother
Answer: A is B\'s father, D is C\'s mother (B\'s wife), so A is D\'s father-in-law.
429
If P→Q, Q→R, R→S, S→T, T→U, U→P, and P is true, then:
Analytical Reasoning
A. All are true
B. All are false
C. Alternating values
D. Cannot determine
Answer: If P is true and they form a cycle, all must be true by modus ponens.
430
If exactly 4 of 6 statements are true, and they form pairs (1↔2, 3↔4, 5↔6), what follows?
Analytical Reasoning
A. Pairs 1-2 and 3-4 are true
B. Pairs 3-4 and 5-6 are true
C. Any two pairs are true
D. All pairs are true
Answer: Since exactly 4 are true and they form equivalence pairs, any two pairs must be true.
431
What is the conclusion? \'Since quantum computing breaks current encryption, and encryption protects financial systems, we must develop quantum-resistant encryption.\'
Analytical Reasoning
A. Quantum computing breaks encryption
B. Encryption protects finances
C. We must develop quantum-resistant encryption
D. Quantum computing is advancing
Answer: The recommendation to develop quantum-resistant encryption is the conclusion.
432
If P↔Q, Q↔R, R↔S, S↔T, and exactly 3 are true, what follows?
Analytical Reasoning
A. P is true
B. T is true
C. Contradiction
D. P and T are false
Answer: Equivalence means all must have the same truth value. Having exactly 3 true is impossible.
433
P∧Q→R, P∧R→Q, Q∧R→P. If P is true and R is false, then:
Analytical Reasoning
A. Q is true
B. Q is false
C. P is false
D. Both Q and R are true
Answer: P∧Q→R and R is false means P∧Q is false. Since P is true, Q must be false.
434
Which strengthens? \'Neural networks learn from data because they adjust weights based on errors.\'
Analytical Reasoning
A. Neural networks process data
B. Weight adjustment reduces errors
C. Error reduction indicates learning
D. All of the above
Answer: For the argument to hold, all these assumptions must be true.
435
All engineers are graduates. Some graduates are programmers. All programmers know coding. Some coders are web developers. Therefore:
Analytical Reasoning
A. All engineers are web developers
B. Some engineers may know coding
C. No engineers know coding
D. All web developers are engineers
Answer: Some engineers are graduates, some graduates are programmers, and all programmers know coding, so some engineers may know coding.
436
A, B, C, D, E are in a line. A is first. C is between B and D. E is last. B is between A and C. What is the order?
Analytical Reasoning
A. A-B-C-D-E
B. A-C-B-D-E
C. A-B-D-C-E
D. A-D-B-C-E
Answer: A first, B between A and C, C between B and D, E last gives A-B-C-D-E.
437
What weakens? \'Blockchain will transform finance because it\'s decentralized and secure.\'
Analytical Reasoning
A. Decentralization is valuable
B. Security is important
C. Current finance is centralized
D. Blockchain is slow
Answer: If blockchain is slow, it may not be practical for transforming finance despite being secure.
438
Which assumption? \'Quantum computing will revolutionize cryptography because it can factor large numbers quickly.\'
Analytical Reasoning
A. Quantum computers can factor quickly
B. Factoring breaks current cryptography
C. Revolution means improvement
D. All of the above
Answer: For the argument to hold, all these assumptions must be true.
439
If A↔B, B↔C, C↔A, and exactly 1 is true, what follows?
Analytical Reasoning
A. A is true
B. B is true
C. C is true
D. Contradiction
Answer: Equivalence means all must have the same truth value. Having exactly 1 true is impossible.
440
P∧Q→R, P∧R→Q, Q∧R→P. If P and Q are true, then:
Analytical Reasoning
A. R is true
B. R is false
C. R is unknown
D. P or Q is false
Answer: P∧Q→R and both P and Q true means R must be true.
