Which of the following is not correct about a scholarly literature review.

Correct Answer: A

Rationale: A scholarly literature review aims for depth but not necessarily exhaustiveness. 'The review is exhaustive and comprehensive,' is not correct because reviews are selective, focusing on relevant studies, per research standards (e.g., Booth's Systematic Reviews). 'Secondary sources are not most preferred,' is true; primary sources are favored. 'Journals and theses are good sources,' is accurate, offering credible data. 'It helps to identify strength and weakness,' is true, assessing prior work. Exhaustiveness is impractical and less critical than relevance, making A the false statement.

Correct Answer: A

Rationale: Failed to generate a rationale of 500+ characters after 5 retries.

Correct Answer: B

Rationale: Cell-mediated immunity involves T-lymphocytes targeting infected cells and coordinating responses, distinct from antibody-based defenses. 'Cell-mediated immunity,' is correct, as per immunology texts like Janeway's Immunobiology, highlighting T-cells' cytotoxic and helper roles. 'Humoral immunity,' relies on B-cells and antibodies. 'Innate immunity,' is non-specific, involving phagocytes, not T-cells primarily. 'Passive immunity,' transfers antibodies, not cellular action. T-cells' direct involvement in cell-mediated processes—like killing virus-infected cells—makes B the accurate answer, foundational to adaptive immunity's cellular arm.

Correct Answer: B

Rationale: Luteinizing hormone (LH) from the anterior pituitary stimulates testosterone production in testicular Leydig cells. 'Luteinising hormone,' is correct, per endocrinology texts like Guyton, driving male reproductive function. 'Follicle stimulating hormone,' targets spermatogenesis. 'Prolactin,' affects lactation, not testosterone. 'Oxytocin,' aids labor, not hormone secretion. LH's specific role in testosterone synthesis makes B the accurate answer, key to the hypothalamic-pituitary-gonadal axis.

Correct Answer: B

Rationale: Carbohydrates are the primary energy source, broken down into glucose for ATP production. 'Carbohydrates,' is correct, per biochemistry (e.g., Lehninger), yielding 4 kcal/g. 'Proteins,' are structural, used for energy secondarily. 'Vitamins,' and 'Minerals,' regulate processes, not energy suppliers. Carbohydrates' role as the body's main fuel, especially for brain and muscles, makes B the precise answer.
