Logical Problems MCQs set 3 for HEC HAT-General (Religious Studies) analytical reasoning — 20 solved questions.
Q1. A 16-year-old athlete feels muscle fatigue during a sprint. Which process is responsible for the rapid ATP production in this situation?
Answer: Phosphocreatine kinase reaction
Explanation: Phosphocreatine kinase reaction rapidly replenishes ATP stores during high-intensity exercise, unlike anaerobic glycolysis.
Q2. A patient with a severe head injury is unconscious. Which part of the brain regulates consciousness?
Answer: Cerebral cortex
Explanation: The cerebral cortex, particularly the prefrontal cortex, is primarily responsible for regulating consciousness.
Q3. A person with a genetic disorder has an increased risk of developing type 2 diabetes. Which genetic disorder is most commonly associated with diabetes?
Answer: MODY (Maturity-Onset Diabetes of the Young)
Explanation: MODY is a genetic disorder that affects insulin production, increasing the risk of developing type 2 diabetes.
Q4. A 20-year-old woman is experiencing difficulty with vision after a head injury. Which part of the brain is responsible for processing visual information?
Answer: Cerebral cortex
Explanation: The primary visual cortex, located in the occipital lobe of the cerebral cortex, processes visual information.
Q5. A person with a rare genetic disorder has an increased risk of developing a blood clot. Which genetic disorder is most commonly associated with blood clots?
Answer: Factor V Leiden
Explanation: Factor V Leiden is a genetic disorder that increases the risk of blood clots due to an abnormal factor V protein.
Q6. A patient with a severe burn injury is experiencing shock. Which system is responsible for maintaining blood pressure in this situation?
Answer: Circulatory system
Explanation: The circulatory system, specifically the heart, is responsible for maintaining blood pressure and perfusing vital organs.
Q7. A person with a rare genetic disorder has an increased risk of developing a type of cancer. Which genetic disorder is most commonly associated with cancer?
Answer: Li-Fraumeni syndrome
Explanation: Li-Fraumeni syndrome is a genetic disorder that increases the risk of developing several types of cancer due to TP53 mutations.
Q8. A patient with a severe head injury is experiencing confusion and disorientation. Which part of the brain is most likely affected?
Answer: Cerebral cortex
Explanation: The cerebral cortex, particularly the prefrontal cortex, is primarily responsible for regulating consciousness and processing sensory information.
Q9. A person with a rare genetic disorder has an increased risk of developing a heart defect. Which genetic disorder is most commonly associated with heart defects?
Answer: Marfan syndrome
Explanation: Marfan syndrome is a genetic disorder that increases the risk of developing heart defects due to abnormalities in the FBN1 gene.
Q10. A patient with a severe infection is experiencing sepsis. Which system is most likely affected?
Answer: Circulatory system
Explanation: The circulatory system, specifically the heart and blood vessels, is most likely affected in sepsis due to inflammation and endothelial damage.
Q11. A patient with a severe head injury is experiencing difficulty with speech. Which part of the brain is most likely affected?
Answer: Cerebral cortex
Explanation: The cerebral cortex, particularly the Broca's area, is primarily responsible for language processing and speech production.
Q12. A patient with a severe infection is experiencing acute kidney injury. Which system is most likely affected?
Answer: Urinary system
Explanation: The urinary system, specifically the kidneys, is most likely affected in acute kidney injury due to inflammation and damage to renal tissue.
Q13. A person with a rare genetic disorder has elevated levels of homocysteine in the blood. This may be due to a deficiency in which enzyme?
Answer: Methionine synthase
Explanation: Methionine synthase deficiency leads to elevated homocysteine levels due to impaired methionine conversion.
Q14. A person who cannot consume lactose as an adult has which type of carbohydrate intolerance?
Answer: Lactose intolerance
Explanation: Lactose intolerance occurs when lactase enzyme is deficient in adults, making it difficult to digest lactose.
Q15. A 30-year-old woman with a history of recurrent miscarriages is diagnosed with a genetic disorder affecting coagulation. Which disorder is this likely to be?
Answer: Factor V Leiden
Explanation: Factor V Leiden increases the risk of thrombosis and recurrent miscarriage due to blood clot formation.
Q16. A patient develops weakness and fatigue due to a toxic substance released during a fire. This substance is most likely to be which compound?
Answer: Carbon monoxide
Explanation: Carbon monoxide has a high affinity for hemoglobin, leading to tissue hypoxia and symptoms of weakness and fatigue.
Q17. A person with a rare condition has an elevated level of a hormone produced in the kidneys. Which hormone is this?
Answer: Erythropoietin
Explanation: Erythropoietin stimulates erythropoiesis, and its levels are typically elevated in chronic kidney disease.
Q18. A person taking a certain medication experiences a severe allergic reaction after taking the medication. Which reaction is this most likely to be?
Answer: Anaphylaxis
Explanation: Anaphylaxis is a severe, life-threatening allergic reaction that can occur within minutes of exposure to an allergen.
Q19. A person with a rare genetic disorder has an excessive amount of a hormone produced in the thyroid gland. Which hormone is this?
Answer: Triiodothyronine
Explanation: Triiodothyronine is the biologically active form of thyroid hormone, and excessive production leads to hyperthyroidism.
Q20. A person experiences severe abdominal pain and fever after consuming a raw egg. Which organism is most likely responsible for this illness?
Answer: Salmonella
Explanation: Salmonella is a common cause of foodborne illness, particularly from consuming raw or undercooked eggs.
