Psychology QUESTION #1459

Which type of learning occurs through observing others and imitating their behaviors?

Classical conditioning
Operant conditioning
Observational learning✔️
Latent learning

Correct Answer Logic:

Observational learning (also called social learning or modelling) occurs by watching and imitating others. Albert Bandura's Social Learning Theory (1977) demonstrated this through his Bobo doll experiments, showing children imitated aggressive behaviour modelled by adults. Classical conditioning involves stimulus-response associations; operant conditioning involves reinforcement/punishment; latent learning occurs without immediate reinforcement.

Mechanical Engineering QUESTION #2438

Question 6

For an underdamped system ($\zeta < 1$), the damped natural frequency $\omega_d$ (quasi-circular frequency $b$) is:

$\omega_d = \omega_n / \sqrt{1-\zeta^2}$
$\omega_d = \omega_n\sqrt{1-\zeta^2}$✔️
$\omega_d = \omega_n(1-\zeta)$
$\omega_d = \omega_n + \zeta$

Correct Answer Logic:

For the underdamped case, the damped natural frequency is $\omega_d=\omega_n\sqrt{1-\zeta^2}$. Since $\zeta<1$, $\omega_d<\omega_n$.

Statistics QUESTION #1979

Question 7

A box contains 4 bad and 6 good tubes. Two tubes are drawn at random. Given that one tested tube is good, the probability that the other is also good using the conditional probability approach is:

$\dfrac{1}{3}$
$\dfrac{5}{9}$
$\dfrac{5}{14}$
$\dfrac{5}{13}$✔️

Correct Answer Logic:

Let A = both good, B = at least one good. $P(A) = \binom{6}{2}/\binom{10}{2} = 15/45 = 1/3$. $P(B) = 1 - P(\text{both bad}) = 1 - \binom{4}{2}/\binom{10}{2} = 1 - 6/45 = 39/45$. But the condition is one specific tube tested is good: $P(\text{other good}|\text{one is good}) = \frac{5}{9}$ using hypergeometric reasoning on remaining 9 tubes (5 good, 4 bad). Answer is $\dfrac{5}{9}$.

Sociology QUESTION #1674

Question 18

The Frankfurt School theorists — particularly Adorno and Horkheimer — introduced the concept of the 'culture industry' to advance which critical argument about mass culture under advanced capitalism?

That capitalist production has successfully democratized access to genuine artistic culture
That mass-produced popular culture functions as a mechanism of ideological domination, standardizing tastes and pacifying critical consciousness✔️
That elite art forms have been displaced by a more egalitarian cultural production
That the decentralization of media has weakened the concentration of political power

Correct Answer Logic:

In 'Dialectic of Enlightenment' (1944), Adorno and Horkheimer argued that the culture industry — the mass production of standardized cultural commodities (film, music, radio) — serves capitalism by commodifying culture, manufacturing false needs, homogenizing taste, and preventing the development of critical consciousness that might challenge the existing social order.
