• A. Use the same formal tone regardless of the audience.
• B. Consider the audience's age, background, and level of knowledge.
• C. Rely on jargon and technical terms to sound professional.
• D. Focus on your own voice and writing preferences.

2. What happens to the work done on an object when the angle between force and displacement is 90 degrees?

• A. Maximum work is done
• B. No work is done
• C. Minimum work is done
• D. Work is infinite

Correct answer: b

Rationale: When the angle between force and displacement is 90 degrees, the work done on the object is zero.

3. Which element makes up the majority of the Earth's atmosphere?

• A. Nitrogen
• B. Oxygen
• C. Carbon dioxide
• D. Argon

Correct answer: A

Rationale: Nitrogen is the most abundant gas in the Earth's atmosphere, crucial for plant life and maintaining the planet's temperature balance.

4. What is the ethical concern surrounding genetic engineering?

• A. Risk of introducing new diseases
• B. Potential for misuse and discrimination
• C. Unforeseen consequences on ecosystems
• D. All of the above

Correct answer: D

Rationale: Rationale: A) Risk of introducing new diseases: Genetic engineering involves manipulating the genetic material of organisms, which can potentially lead to the creation of new diseases or the spread of existing ones in unintended ways. This risk raises ethical concerns about the potential harm to human health and the environment. B) Potential for misuse and discrimination: Genetic engineering technologies can be misused for purposes such as creating biological weapons or enhancing certain traits in individuals, leading to discrimination based on genetic makeup. This raises ethical concerns about fairness, justice, and the potential for societal harm. C) Unforeseen consequences on ecosystems: Genetic engineering can have unintended consequences on ecosystems, such as disrupting natural balances or harming biodiversity. These unforeseen impacts raise ethical concerns about the responsibility of scientists and policymakers to consider the long-term effects of genetic modifications on th

5. Which type of mutation involves a change in the number of chromosomes?

• A. Point mutation
• B. Frameshift mutation
• C. Missense mutation
• D. Aneuploidy

Correct answer: D

Rationale: Rationale: A) Point mutation: Involves a change in a single nucleotide base pair within the DNA sequence. B) Frameshift mutation: Involves the insertion or deletion of nucleotides, causing a shift in the reading frame of the genetic code. C) Missense mutation: Involves a single nucleotide change that results in a codon that codes for a different amino acid. D) Aneuploidy: Involves a change in the number of chromosomes, where an individual may have an extra chromosome (trisomy) or a missing chromosome (monosomy). Aneuploidy can lead to genetic disorders such as Down syndrome (trisomy 21) or Turner syndrome (monosomy X).

6. What is the main verb tense in the following sentence? "She had already left before I arrived."
