1. 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.'

2. Which element is considered a noble gas?

• A. Oxygen
• B. Neon
• C. Hydrogen
• D. Argon

Correct answer: B

Rationale: The correct answer is 'Neon.' Noble gases are a group of elements with very low reactivity. Neon is one of these elements, known for its stable and unreactive nature. Oxygen, hydrogen, and argon do not belong to the noble gas group. Oxygen is a reactive non-metal, hydrogen is a non-metal and the first element in the periodic table, and argon is a noble gas like neon but not the correct answer in this case.

3. Which of the following elements is the most electronegative?

• A. Oxygen
• B. Fluorine
• C. Nitrogen
• D. Sodium

Correct answer: B

Rationale: Fluorine is the most electronegative element on the periodic table. It has the highest electronegativity value, indicating its strong ability to attract electrons in a chemical bond. This property makes it highly reactive, explaining why it is the correct answer in this question. Oxygen and Nitrogen are also electronegative elements, but they are not as electronegative as Fluorine. Sodium, on the other hand, is not electronegative; it is an electropositive element.

4. What is the probability of rolling a 4 on a six-sided die?

• A. 1/2
• B. 1/6
• C. 1/3
• D. 1/2

Correct answer: B

Rationale: The correct answer is B: 1/6. When rolling a six-sided die, there is only one outcome that results in a '4' out of a total of six possible outcomes (1, 2, 3, 4, 5, 6). Therefore, the probability of rolling a 4 is 1/6. Choice A (1/2) is incorrect as it represents the probability of rolling an even number on a six-sided die, not specifically a '4.' Choice C (1/3) and Choice D (1/2) do not accurately reflect the probability of rolling a '4' on a six-sided die.

5. What are proteins made up of?

• A. Fatty acids
• B. Amino acids
• C. Nucleotides
• D. Sugars

Correct answer: B

Rationale: Proteins are made up of amino acids. Amino acids are the building blocks of proteins, essential for various biological processes in the body such as enzyme function, transport, and structural support. Fatty acids (Choice A) are components of lipids, not proteins. Nucleotides (Choice C) are the building blocks of nucleic acids like DNA and RNA, not proteins. Sugars (Choice D) are carbohydrates and are not the primary components of proteins.
