1. An element with atomic number 26 and mass number 56 is most likely to be:

• A. Iron (Fe)
• B. Cobalt (Co)
• C. Nickel (Ni)
• D. Manganese (Mn)

Correct answer: A

Rationale: Iron (Fe) - Fe-56 has 26 protons and aligns with the given atomic number and mass number.

2. What type of error occurs in the sentence "Everyone knew who the culprit was, except for me"?

• A. Subject-verb agreement
• B. Misplaced modifier
• C. Dangling participle
• D. Pronoun-antecedent agreement

Correct answer: B

Rationale: The phrase "except for me" modifies "everyone," but it is misplaced after the verb "knew," causing confusion.

3. The term "unconditional" in the context of UBI signifies that

• A. The amount received would be based on individual income and living expenses.
• B. Recipients would be required to meet certain criteria to qualify for the program.
• C. The money would be provided without any restrictions on how it is spent.
• D. The program would be temporary and subject to periodic review and renewal.

Correct answer: C

Rationale: The unconditional aspect of UBI refers to the lack of strings attached to its receipt, aligning with C.

4. What is the role of RNA interference in silencing genes?

• A. Increases protein production
• B. Promotes gene mutation
• C. Inhibits the expression of specific genes
• D. Repairs damaged DNA

Correct answer: C

Rationale: Rationale: RNA interference (RNAi) is a biological process that involves the silencing of gene expression by inhibiting the translation of mRNA or by degrading mRNA molecules. This mechanism plays a crucial role in regulating gene expression and can be used to selectively silence specific genes. By interfering with the expression of specific genes, RNAi can downregulate protein production from those genes. Therefore, option C, "Inhibits the expression of specific genes," is the correct role of RNA interference in silencing genes.

5. What type of waves require a medium (solid, liquid, or gas) to propagate?

• A. Transverse waves
• B. Longitudinal waves
• C. Electromagnetic waves
• D. Surface waves

Correct answer: B

Rationale: Longitudinal waves require a medium (solid, liquid, or gas) to propagate because the particles in the medium move parallel to the direction of the wave. Transverse waves, on the other hand, do not require a medium and can propagate through a vacuum. Electromagnetic waves also do not require a medium for propagation, as they consist of oscillating electric and magnetic fields. Surface waves are a combination of both longitudinal and transverse waves and also require a medium to propagate.

6. How does the acceleration of an object change if the force acting on it is doubled?

• A. Acceleration is halved
• B. Acceleration doubles
• C. Acceleration remains unchanged
• D. Acceleration quadruples

Correct answer: b

Rationale: According to Newton's second law (F = ma), if force is doubled and mass remains constant, acceleration doubles.
