Reading
1. What is the main concern the author raises about AI?
- A. Its limitations in achieving true intelligence and emulating human consciousness.
- B. Its potential for misuse in warfare and autonomous weapons systems.
- C. Its detrimental impact on the environment and resource consumption.
- D. Its ethical implications related to bias, privacy, and job displacement.
Correct answer: D
Rationale: The passage explicitly mentions concerns about bias, privacy, and job displacement, making D the main concern highlighted.
2. Which hormone, produced by the thyroid gland, plays a key role in regulating calcium levels in the blood by promoting calcium release from bones and increasing calcium reabsorption in the kidneys?
- A. Calcitonin
- B. Parathyroid hormone (PTH)
- C. Thyroxine
- D. Insulin
Correct answer: b
Rationale: The correct answer is B: Parathyroid hormone (PTH). PTH is produced by the parathyroid glands, not the thyroid gland. PTH plays a crucial role in regulating calcium levels in the blood by promoting calcium release from bones and increasing calcium reabsorption in the kidneys. This hormone acts in opposition to calcitonin, which is produced by the thyroid gland and works to lower blood calcium levels by promoting calcium deposition into bones. Thyroxine (C) is a thyroid hormone that regulates metabolism, not calcium levels. Insulin (D) is a hormone produced by the pancreas that regulates blood sugar levels, not calcium levels.
3. Which sentence uses comma splices incorrectly?
- A. The baker kneaded the dough, flour dusted her apron, and the oven warmed up.
- B. The mountains, shrouded in mist, seemed to disappear into the clouds.
- C. He arrived late, having forgotten his keys, and the meeting had already started.
- D. The movie, despite its flaws, was surprisingly enjoyable.
Correct answer: C
Rationale: Option (c) incorrectly combines two independent clauses with only a comma. A semicolon or conjunction is needed
4. Which organ helps break down food by grinding it with your teeth?
- A. Stomach
- B. Esophagus
- C. Liver
- D. Mouth
Correct answer: D
Rationale: Rationale: The mouth is the organ that helps break down food by grinding it with your teeth. The process of chewing, also known as mastication, breaks down food into smaller pieces, making it easier to swallow and digest. The teeth in the mouth play a crucial role in this initial stage of digestion by physically breaking down food into smaller particles. The other options listed do not directly participate in the mechanical breakdown of food through chewing.
5. The two main divisions of the skeletal system are:
- A. Upper and lower body bones
- B. Axial and appendicular skeleton
- C. Long and short bones
- D. Compact and spongy bone
Correct answer: B
Rationale: The correct answer is B: Axial and appendicular skeleton. The skeletal system is divided into two main parts: the axial skeleton, which includes the skull, rib cage, and vertebral column, and the appendicular skeleton, which includes the bones of the arms, legs, shoulders, and hips. This division is based on the location and function of the bones in the body. The other options are incorrect as they do not represent the main divisions of the skeletal system. Understanding these divisions is important for studying the structure and function of the human skeletal system.
6. What is the relationship between the frequency and wavelength of a wave?
- A. Inversely proportional
- B. Directly proportional
- C. No relationship
- D. Depend on the medium
Correct answer: a
Rationale: Frequency and wavelength have an inverse relationship - as one increases, the other decreases.
