1. What is the scientific name for the common housefly?
- A. Musca domestica
- B. Drosophila melanogaster
- C. Apis mellifera
- D. Anopheles gambiae
Correct answer: A
Rationale: Rationale: - Musca domestica is the scientific name for the common housefly. This species is known for being a common pest found in and around human habitations. - Drosophila melanogaster (option B) is a species of fruit fly commonly used in genetic research. - Apis mellifera (option C) is the scientific name for the western honeybee. - Anopheles gambiae (option D) is a species of mosquito known for being a vector of malaria.
2. The ball-and-socket joint, which allows for wide range of motion, is found in the connection between:
- A. Upper arm and shoulder blade (scapula)
- B. Collarbone (clavicle) and breastbone (sternum)
- C. Two vertebrae in the spine
- D. Ribs and sternum
Correct answer: A
Rationale: The correct answer is A: 'Upper arm and shoulder blade (scapula).' The ball-and-socket joint is found in the connection between the humerus (upper arm bone) and the scapula (shoulder blade). This joint allows for a wide range of motion, including flexion, extension, abduction, adduction, and rotation. The collarbone (clavicle) and breastbone (sternum) are connected by a cartilaginous joint, not a ball-and-socket joint. Two vertebrae in the spine are connected by facet joints, and the ribs and sternum are connected by cartilaginous joints and the costovertebral joints. Therefore, the ball-and-socket joint is uniquely found in the connection between the upper arm and the shoulder blade, allowing for the shoulder's impressive range of motion.
3. The author's attitude towards history seems to be
- A. indifferent and neutral, presenting it as an objective field of study.
- B. critical and dismissive, questioning its practical applicability in the present.
- C. enthusiastic and optimistic, highlighting its potential to guide the future.
- D. pessimistic and cautious, emphasizing the risk of repeating past mistakes.
Correct answer: C
Rationale: The passage's overall tone highlights the value and utility of history, showcasing its potential to inspire and guide us, suggesting an optimistic and encouraging view.
4. Identify the comprehensive protection for the brain.
- A. Skull
- B. Meninges (Membranes)
- C. Cerebrospinal fluid
- D. All of the above
Correct answer: D
Rationale: Rationale: A) The skull provides a hard, protective covering for the brain, shielding it from external trauma and injury. B) The meninges are three layers of membranes (dura mater, arachnoid mater, and pia mater) that surround the brain and spinal cord, providing additional protection and cushioning. C) Cerebrospinal fluid is a clear, colorless fluid that surrounds the brain and spinal cord, acting as a shock absorber and providing nutrients to the central nervous system. Together, the skull, meninges, and cerebrospinal fluid work in conjunction to provide comprehensive protection for the brain, making option D the correct answer.
5. Histamine, released during an allergic reaction, causes symptoms like:
- A. Fever and fatigue
- B. Runny nose and itchiness
- C. Muscle aches and joint pain
- D. Cough and shortness of breath
Correct answer: B
Rationale: The correct answer is B: 'Runny nose and itchiness.' Histamine is a chemical released by the body during an allergic reaction. It causes various symptoms such as itching, sneezing, runny nose, and watery eyes. These symptoms are commonly associated with allergic reactions like hay fever or hives. Fever and fatigue (option A) are not directly caused by histamine release. Muscle aches and joint pain (option C) are not typical symptoms of histamine release during an allergic reaction. Cough and shortness of breath (option D) are more commonly associated with asthma or respiratory allergies rather than histamine release.
6. What is the main function of transition words and phrases in writing?
- A. To add unnecessary embellishments and fluff.
- B. To emphasize specific words or phrases in the text.
- C. To connect ideas smoothly and guide the reader's flow.
- D. To introduce opposing viewpoints and counterarguments.
Correct answer: C
Rationale: Transition words and phrases bridge ideas, create logical flow, and enhance the coherence of your writing.
