True about eating:

Correct Answer: A

Rationale: Cold weather activatlateral hypothalamus . Cold temperaturstimulate the lateral hypothalamus (LH) to increase food intake for thermogenesis, per physiological studies. Choice B is false; an empty stomach activatthe LH, not the ventromedial hypothalamus (satiety center). Choice C is incorrect; high blood sugar suppresshunger via insulin and leptin signaling. Choice D is wrong; insulin increasappetite by lowering glucose, not decreasing intake. is false; exercise aids weight loss by burning calories. As truth is rooted in adaptive physiology cold triggers LH-driven eating to maintain body heat, as seen in animal models, making it the correct answer.

Correct Answer: B

Rationale: Vulnerability , which is not a Big Five trait. The Big Five are Openness, Conscientiousness, Extraversion , Agreeableness , and Neuroticism (opposite of emotional stability, A). Vulnerability is a facet of Neuroticism, not a standalone trait. Choice A (emotional stability) reflects low Neuroticism; C (extraversion) sociability; D (openness) creativity; E (agreeableness) cooperation. Bs exclusion being a sub-trait, not a core dimension aligns with the Big Five model (Costa & McCrae), widely validated in personality research, making it the correct answer over the established traits A, C, D, E.

Correct Answer: A

Rationale: Objective personality tests assess conscious personality aspects . Tests like MMPI measure self-reported, conscious traits (e.g., extraversion), unlike projective tests. Choice B is false; Rogers focused on self-concept, not Freuds ego/superego. Choice C is incorrect; trait theory (e.g., Big Five) describtraits, not neurodevelopment specifically. Choice D is wrong; Freud used psychoanalysis (unconscious drives), not self-actualization (Maslow). is partially true but vague personality stabilizin adulthood. As truth objective tests focus on accessible traits contrasts with theoretical errors in B-D and ambiguity, making it the correct answer.

Correct Answer: C

Rationale: Blood sugar level affects appetite and food intake . Low glucose triggers hunger via the lateral hypothalamus, while high levels signal satiety, per glucostatic theory. Choice A is false; cold increasintake. Choice B is wrong; insulin increashunger by lowering glucose. Choice D is incorrect; multiple systems (e.g., gut, brain) regulate intake. is false; the lateral hypothalamus drivhunger, not satiety. Cs truth glucosrole in appetite is foundational, unlike the reversed or narrow claims of A, B, D, E, making it the correct answer.

Correct Answer: A

Rationale: Exercise is more important for weight loss in overweight individuals . Exercise burns caloriand boosts metabolism, critical for overweight people, per obesity guidelines. Choice B is false; behavior therapy (e.g., CBT) aids weight control. Choice C is incorrect; metabolic rate decreasin deprivation to conserve energy. Choice D is wrong; basal metabolism is ~60-70% of expenditure, not one-third. is false; psychology (e.g., motivation) is key. As truth exercisoutsized role in calorie deficit contrasts with the errors of B-E, making it the correct answer.
