DCOA Mixed Practice Test #33

Question 1

A student consistently performs exceptionally well across diverse academic subjects like Mathematics, Literature, and Science, and also demonstrates quick learning in extracurricular activities such as chess and debate. According to Charles Spearman's theory of intelligence, this broad pattern of high achievement is best explained by the presence of a strong:

Accepted Answer

C. General intelligence factor (g-factor) underlying all cognitive tasks. — Spearman's 'g-factor' represents a general mental ability that underlies and influences performance on a wide range of cognitive tasks. The student's consistent high performance across diverse areas suggests a strong underlying general intelligence, rather than just specific abilities (s-factor) or constructs from other theories.

Answer

A. Specific factor (s-factor) for each individual domain.

Answer

B. Crystallized intelligence derived from extensive learning.

Answer

D. Multiple intelligences working in harmony.

Question 2

A teacher observes that a student consistently performs well across subjects like mathematics, literature, and science, easily grasping new concepts in each domain. According to Spearman's Two-Factor Theory of Intelligence, this student likely possesses a high degree of:

Accepted Answer

B. General intelligence (G-factor). — Spearman's Two-Factor Theory posits a general intelligence (G-factor) that underlies all cognitive abilities, explaining why individuals might perform consistently well across various tasks. While specific abilities (S-factors) exist, the consistent high performance across diverse subjects points to a strong G-factor. Gardner's theory suggests distinct intelligences, and Sternberg's contextual intelligence relates to practical adaptation, neither directly explaining a unified high performance across academic subjects in Spearman's terms.

Answer

A. Specific abilities (S-factors) in multiple domains.

Answer

C. Multiple intelligences as proposed by Gardner.

Answer

D. Contextual intelligence as described by Sternberg.

Question 6

Acetylcholine is a key neurotransmitter in the nervous system. In which part of the autonomic nervous system is acetylcholine the primary neurotransmitter released by postganglionic neurons at their target organs?

Accepted Answer

B. Parasympathetic nervous system — In the parasympathetic nervous system, acetylcholine is the neurotransmitter released by both preganglionic and postganglionic neurons at their target organs, mediating 'rest and digest' responses. In contrast, the sympathetic nervous system primarily uses norepinephrine at its postganglionic synapses (except for sweat glands). The somatic nervous system is voluntary and uses acetylcholine at neuromuscular junctions, while the central nervous system uses a wide array of neurotransmitters.

Answer

A. Sympathetic nervous system

Answer

C. Somatic nervous system

Answer

D. Central nervous system

Question 8

Rapid urbanization in developing countries often leads to significant social changes, including shifts in lifestyle and environment. From a community health perspective, which of the following health issues is most likely to show a marked increase as a direct consequence of these changes?

Accepted Answer

B. Prevalence of non-communicable diseases (NCDs) such as diabetes and hypertension. — Rapid urbanization often leads to lifestyle changes like sedentary behavior, consumption of processed foods, increased stress, and environmental pollution. These factors are major contributors to the rising prevalence of non-communicable diseases (NCDs) such as diabetes, hypertension, and cardiovascular diseases, even in developing countries. While communicable diseases can persist or emerge due to overcrowding, NCDs are a characteristic health challenge of urbanized populations resulting from lifestyle shifts.

Answer

A. Incidence of vector-borne diseases like dengue and malaria due to improved housing.

Answer

C. Rates of acute respiratory infections due to decreased air pollution from industrialization.

Answer
