1. What is the main idea of the following passage: "The internet has revolutionized communication, allowing people to connect instantly from anywhere in the world. Social media platforms, like Facebook and Twitter, have further amplified this connectivity, enabling individuals to share information and ideas on a global scale."

• A. The internet is a source of entertainment.
• B. Social media is the only way to communicate online.
• C. The internet has transformed communication globally.
• D. Technology is becoming increasingly complex.

Correct answer: C

Rationale: The passage emphasizes the transformative impact of the internet and social media on communication.

2. A water wave approaches a shallow beach. What happens to its speed, wavelength, and frequency?

• A. Speed increases, wavelength decreases, frequency increases.
• B. Speed decreases, wavelength decreases, frequency remains the same.
• C. Speed increases, wavelength increases, frequency decreases.
• D. Speed, wavelength, and frequency remain the same.

Correct answer: B

Rationale: As waves enter shallow water, they slow down due to increased interaction with the bottom. This causes the wavelength to decrease to maintain the constant wave energy (E = hf). Frequency remains constant as it's determined by the source, not the medium.

3. The phenomenon responsible for the creation of rainbows is:

• A. Reflection only
• B. Diffraction
• C. Refraction and reflection
• D. Polarization

Correct answer: C

Rationale: The correct answer is C: Refraction and reflection. Rainbows are formed when sunlight is refracted and reflected inside raindrops. The sunlight entering the raindrop is refracted, then internally reflected off the back surface of the droplet, and finally refracted again as it exits the droplet. This dispersion of light causes the separation of colors we see in a rainbow. Reflection alone (option A) does not account for the formation of rainbows. Diffraction (option B) is the bending of light around obstacles, not the main mechanism behind rainbows. Polarization (option D) refers to the orientation of light waves, which is not the primary process involved in creating rainbows.

4. Which group of elements is known for their reactivity and ability to form strong bonds with other elements?

• A. Noble gases
• B. Halogens
• C. Alkali metals
• D. Transition metals

Correct answer: B

Rationale: Rationale: Halogens are a group of elements in the periodic table that are known for their high reactivity and ability to form strong bonds with other elements. They have seven valence electrons, which makes them highly reactive as they only need one more electron to achieve a stable electron configuration. Halogens readily form compounds with other elements by gaining an electron to achieve a full outer shell, resulting in the formation of strong covalent bonds. In contrast, noble gases (option A) are known for their inertness and stable electron configurations, alkali metals (option C) are highly reactive but not as strong bond formers as halogens, and transition metals (option D) are known for their variable oxidation states and ability to form complex ions but are not as reactive as halogens in terms of bond formation.

5. What is the name of the sheath of connective tissue that surrounds a skeletal muscle?

• A. Epimysium
• B. Perimysium
• C. Endomysium
• D. Myofibril

Correct answer: A

Rationale: The correct answer is A: Epimysium. The epimysium is the outermost layer of connective tissue that surrounds a skeletal muscle. It provides protection and support to the muscle fibers within, as well as helps in transmitting forces generated by the muscle. Perimysium (B) is the connective tissue that surrounds bundles of muscle fibers called fascicles, while endomysium (C) is the connective tissue that surrounds individual muscle fibers. Myofibril (D) is a structure within muscle fibers that contains the contractile units responsible for muscle contraction. Therefore, in this context, the sheath of connective tissue surrounding a skeletal muscle is specifically referred to as the epimysium.

6. What is the main argument presented in favor of UBI?

• A. It would boost the economy by increasing consumer spending and stimulating businesses.
• B. It would guarantee financial stability and improve mental health for all citizens.
• C. It would address ethical concerns about income inequality and promote social justice.
• D. It would decrease crime rates and improve public safety by reducing poverty and desperation.

Correct answer: C

Rationale: The passage emphasizes UBI's potential to alleviate poverty and reduce inequality, aligning with C.
