Question 1

A student consistently scores high marks in diverse subjects like Mathematics, English literature, and Physics, demonstrating a strong underlying cognitive ability across these areas. According to Charles Spearman's theory of intelligence, this consistent high performance is best explained by the presence of a strong:

Accepted Answer

B. General factor (g-factor) — Spearman's theory posits a 'g-factor' (general intelligence) that underlies performance across various cognitive tasks, and 's-factors' (specific intelligence) unique to particular tasks. The student's consistent high performance across diverse subjects indicates a strong general cognitive ability, which is the g-factor. Specific factors would account for variations in performance on individual tasks, not overall consistency.

Answer

A. Specific factor (s-factor)

Answer

C. Multiple intelligences

Answer

D. Practical intelligence

Question 2

Alkaloids are generally characterized by their basic nature, which is primarily due to the presence of:

Accepted Answer

Question 9

Which type of glass is preferred for packaging parenteral solutions due to its high hydrolytic resistance and low alkali content?

Accepted Answer

A. Type I (borosilicate glass) — Type I borosilicate glass is preferred for parenteral solutions because it has the highest hydrolytic resistance and lowest alkali content, minimizing interaction with the drug. Type II glass is treated for reduced leaching but is not as resistant as Type I.
