1. Which of the following is NOT a factor affecting the rate of a chemical reaction?

Correct answer: D

Rationale: The color of the reaction mixture is not a factor affecting the rate of a chemical reaction. Factors such as the concentration of reactants, temperature, and the presence of a catalyst can influence the rate of a chemical reaction by affecting the frequency of collisions between reactant molecules and the energy of those collisions. The color of the reaction mixture is a physical property and does not directly impact the kinetics or speed of the reaction process. It is a qualitative observation that does not alter the reaction rate or mechanisms involved.

2. Which term describes the resistance of a substance to being hammered into different shapes?

Correct answer: C

Rationale: Malleability is the property that allows a substance to be hammered or rolled into thin sheets without breaking. It is the opposite of brittleness. Ductility refers to the ability of a material to be drawn into thin wires, not hammered into shapes. Viscosity is the measure of a fluid's resistance to flow, indicating how thick or sticky it is, not related to shaping by hammering. Conductivity refers to the ability of a material to conduct electricity or heat, not resistance to being hammered into different shapes.

3. This passage describes characters' feelings in Madame Butterfly as all of the following EXCEPT:

Correct answer: D

Rationale: The passage describes the characters' feelings in Madame Butterfly as romantic, poignant, and tragic, but not musical. The story depicts the emotional aspects of love, heartbreak, and tragedy, evoking strong feelings of romance, sadness, and tragedy. While music plays a crucial role in the opera Madame Butterfly, the characters' feelings are not specifically described as musical, making choice D the correct answer. Choices A, B, and C are supported by the emotional context provided in the extract.

4. What is the main function of the endoplasmic reticulum (ER) in the cell?

Correct answer: A

Rationale: The endoplasmic reticulum (ER) is a network of membranes within the cell that plays a crucial role in protein and lipid synthesis. It consists of two types: rough ER, which is studded with ribosomes and involved in protein synthesis, and smooth ER, which is involved in lipid synthesis and detoxification. The ER's main function is to synthesize proteins and lipids, not just package and transport them. While the ER is involved in transporting these synthesized proteins and lipids to other parts of the cell or outside the cell, its primary role is in their synthesis. Breaking down macromolecules is primarily the function of lysosomes, which are membrane-bound organelles containing enzymes for digestion. Storing genetic material is the function of the nucleus, which houses the cell's DNA. The ER is not involved in storing genetic material.

5. Convert 0.1 liter to milliliters.

Correct answer: B

Rationale: To convert 0.1 liters to milliliters, you need to multiply by 1000, not 10000. Therefore, 0.1 liter converts to 100 ml. Choice A (10 ml) is incorrect because it is the equivalent of 0.01 liter. Choice C (1000 ml) is incorrect as it represents 1 liter. Choice D (1 ml) is significantly less than the correct conversion.
