1. Which type of waves do not require a medium for propagation?

• A. Transverse waves
• B. Longitudinal waves
• C. Electromagnetic waves
• D. Surface waves

Correct answer: C

Rationale: Electromagnetic waves do not require a medium for propagation as they consist of oscillating electric and magnetic fields that can travel through a vacuum. This property allows electromagnetic waves, such as light, radio waves, and X-rays, to propagate through space. In contrast, transverse and longitudinal waves require a medium (solid, liquid, or gas) for propagation. Transverse waves have vibrations perpendicular to the direction of energy transfer, while longitudinal waves have vibrations parallel to the direction of energy transfer. Surface waves, which are a combination of transverse and longitudinal waves, also need a medium for propagation. Understanding the distinction between these wave types is essential in various fields, including physics and communication technologies.

2. Which of the following is the most likely setting of the scenario below? Walking along the Thames, Julianna saw a sign advertising a fish and chips shop. Since she felt a bit peckish, she made her way over to the queue.

• A. Chicago, United States
• B. Vienna, Austria
• C. Tokyo, Japan
• D. London, England

Correct answer: D

Rationale: The mention of the Thames, fish and chips, and queue strongly indicates a British setting. Fish and chips are a traditional British dish, and the Thames is a famous river in London, England. Additionally, forming a queue is a common practice in England. Therefore, based on these cultural clues, London, England, is the most likely setting of the scenario. Choices A, B, and C are incorrect as they do not align with the specific cultural references mentioned in the scenario.

3. Based on the analysis of word parts, what is the meaning of the word 'bibliophile'?

• A. A person who collects books
• B. An index at the back of a book
• C. A compiled list of different books
• D. A place where books are kept

Correct answer: A

Rationale: The correct answer is A. The term 'bibliophile' is derived from the Greek words 'biblio' meaning books and 'phile' meaning lover or enthusiast. Therefore, a 'bibliophile' refers to a person who collects or has a great love of books. Choices B, C, and D are incorrect because they do not accurately reflect the meaning of 'bibliophile.' An index at the back of a book is called a 'bibliography,' a compiled list of different books is a 'catalog,' and a place where books are kept is a 'library,' not a 'bibliophile.'

4. Which brain structure is responsible for processing visual information?

• A. Cerebrum
• B. Occipital lobe
• C. Frontal lobe
• D. Brainstem

Correct answer: B

Rationale: The corrected question and choices are accurate. The correct answer is the Occipital lobe. The occipital lobe, located at the back of the brain, is primarily responsible for processing visual information received from the eyes. It plays a crucial role in interpreting and making sense of visual stimuli, allowing us to perceive and understand the world around us. The other choices, cerebrum (A), frontal lobe (C), and brainstem (D), do not have the primary function of processing visual information. The cerebrum is involved in higher brain functions, the frontal lobe is responsible for decision-making and personality, and the brainstem controls basic life functions like breathing and heart rate.

5. Which macromolecule will always contain nitrogen?

• A. Fatty acid
• B. Protein
• C. Lipid
• D. Carbohydrate

Correct answer: B

Rationale: The correct answer is B: Protein. Proteins always contain nitrogen, as it is a key element in amino acids, the building blocks of proteins. Fatty acids (choice A), lipids (choice C), and carbohydrates (choice D) do not always contain nitrogen. Fatty acids consist of long chains of hydrocarbons, lipids are mainly composed of carbon, hydrogen, and oxygen, and carbohydrates are composed of carbon, hydrogen, and oxygen as well, but not nitrogen.
