1. Which branch of chemistry deals with the quantities and numeric relationships between compounds in a chemical reaction?

• A. Stoichiometry
• B. Molecular chemistry
• C. Atomic chemistry
• D. Thermodynamics

Correct answer: A

Rationale: Stoichiometry is the branch of chemistry that deals with the quantitative relationships between reactants and products in chemical reactions. It involves the calculation of quantities of substances consumed and produced in a chemical reaction based on the balanced chemical equation. Choice B, 'Molecular chemistry,' is incorrect as it focuses on the structure, properties, and reactions of molecules. Choice C, 'Atomic chemistry,' is incorrect as it primarily deals with the study of atoms and their interactions. Choice D, 'Thermodynamics,' is incorrect as it pertains to the study of energy and heat transfer in chemical and physical processes.

2. Select the meaning of the word 'amalgamate' in the sentence: 'If the companies amalgamate, some employees may lose their jobs.'

• A. Disband
• B. Move
• C. Merge
• D. Regroup

Correct answer: C

Rationale: The word 'amalgamate' in the sentence indicates that if the companies come together, combine, or unite as one entity, which aligns with the meaning of 'merge.' Amalgamation often refers to the merging or combining of two or more entities into one. 'Disband' (Choice A) means to break up or dissolve, which is opposite to what happens when companies amalgamate. 'Move' (Choice B) and 'Regroup' (Choice D) are not directly related to the process of companies amalgamating or merging.

3. Select the meaning of the quoted word in the sentence. That is an 'ominous' sign.

• A. A good omen
• B. Without deceit
• C. Threatening
• D. Full of thought

Correct answer: C

Rationale: The correct meaning of 'ominous' is 'threatening' or indicating something bad is about to happen. A is incorrect because 'ominous' does not signify a good omen. B is incorrect as 'ominous' does not relate to deceit. D is incorrect as 'ominous' does not mean 'full of thought.' Therefore, the most suitable interpretation of 'ominous' in the given sentence is 'Threatening.'

4. What is the effect of the Earth's rotation on the atmosphere and on all objects on the Earth's surface?

• A. The Coriolis effect
• B. The Corona effect
• C. The Archimedes effect
• D. The tidal effect

Correct answer: A

Rationale: The Coriolis effect is the effect of the Earth's rotation on the atmosphere and on all objects on the Earth's surface. It causes moving objects and currents to be deflected to the right in the northern hemisphere and to the left in the southern hemisphere. This deflection is a result of the rotation of the Earth and plays a crucial role in influencing weather patterns and ocean currents around the globe. The other choices provided are incorrect. The Corona effect is related to the Sun's atmosphere, the Archimedes effect involves buoyancy in fluids, and the tidal effect is associated with the gravitational forces between the Earth, the Moon, and the Sun.

5. In a local baseball team, 4 players, which represent 5% of the team, have long hair, and the rest have short hair. How many short-haired players are there on the team?

• A. 72
• B. 74
• C. 76
• D. 78

Correct answer: C

Rationale: Given that 4 players represent 5% of the team, let's denote the total number of players as x. The equation to represent this situation is 0.05x = 4. Solving for x, we get x = 80, which is the total number of players on the team. Since 4 players have long hair, the remaining players have short hair, which is 80 - 4 = 76. Therefore, there are 76 short-haired players on the team. Choices A, B, and D are incorrect as they do not consider the total number of players correctly, leading to inaccurate calculations.
