MBBS QUESTION #10191

Question 3782

Transposition of the great arteries results from an abnormality in which developmental process during heart formation?

Straight (non-spiral) partitioning of the truncus arteriosus by the aorticopulmonary septum✔️
Failure of closure of the interventricular septum
Failure of fusion of the endocardial cushions
Abnormal development of the sinus venosus

Correct Answer Logic:

Normally the aorticopulmonary septum spirals as it divides the truncus arteriosus, positioning the aorta and pulmonary trunk in their crossing relationship. When this septum forms straight rather than spirally, the aorta arises from the right ventricle and the pulmonary trunk from the left — transposition of the great arteries.

Administration QUESTION #9562

Question 3783

Herbert Simon argued that organizations are important because they shape the decision-making environment of individuals. He classified administrative behaviour into three streams. Which classification best explains why two equally qualified officers in different ministries might reach different decisions on the same policy problem?

Different levels of charismatic authority make them susceptible to different interpersonal influences
The structure of their respective organizations determines the environments of information available to them — different bureaucratic contexts produce different cognitive inputs for decision-making✔️
The difference in their personal Theory X or Theory Y orientation leads to fundamentally different analytical frameworks
Different stages in their Maslow hierarchy of needs cause them to weight policy outcomes according to their dominant personal need

Correct Answer Logic:

Simon argued that organizations structure the decision environment — they filter information, establish premises of decision and shape the range of alternatives considered. Two officers in different organizational contexts will have different information environments, different standard operating procedures and different institutional premises — leading to divergent decisions even with identical professional qualifications.

Psychology QUESTION #9770

Question 3784

Group intelligence testing is considered superior to individual intelligence testing.

True
False✔️
Sometimes
Depends on age group

Correct Answer Logic:

False. Individual testing (e.g., Wechsler scales) is more accurate because examiners can observe behaviour, establish rapport, and adapt to the individual. Group tests sacrifice precision for efficiency.

Boilers Mechanical Engineering QUESTION #2510

Question 3785

For a state of plane stress $(\sigma_x, \sigma_y, \tau_{xy})$, the maximum in-plane shear stress is:

$\tau_{max} = \sqrt{\left(\frac{\sigma_x - \sigma_y}{2}\right)^2 + \tau_{xy}^2}$✔️
$\tau_{max} = \frac{\sigma_x + \sigma_y}{2}$
$\tau_{max} = \sigma_x - \sigma_y$
$\tau_{max} = \tau_{xy}$

Correct Answer Logic:

The maximum in-plane shear stress equals the radius of Mohr's circle: $\tau_{max}=\sqrt{\left(\frac{\sigma_x-\sigma_y}{2}\right)^2+\tau_{xy}^2}$.

Psychology QUESTION #9735

Question 3789

Howard Gardner's Theory of Multiple Intelligences challenges the concept of a single IQ score by proposing several independent intelligences. Which of the following is NOT one of Gardner's originally proposed intelligences?

Linguistic intelligence
Emotional intelligence✔️
Musical intelligence
Bodily-kinesthetic intelligence

Correct Answer Logic:

Emotional Intelligence was not part of Howard Gardner's original eight intelligences. Gardner originally proposed: Linguistic, Logical-Mathematical, Spatial, Musical, Bodily-Kinesthetic, Interpersonal, Intrapersonal, and Naturalistic intelligences (a ninth — Existential — was later proposed tentatively). Emotional intelligence was popularized by Daniel Goleman and is related to but separate from Gardner's framework.

Journalism / Mass Communication QUESTION #6386

Question 3795

The Lumière Brothers of France are credited with creating the first projection device for motion pictures in 1895. What was the name of this device, and where was the first public screening in the Indian subcontinent held?

Kinetoscope; first screening at the Victoria Hall, Calcutta on 12 August 1896
Cinématographe; first screening at Watson Hotel, Bombay on 7 July 1896✔️
Vitascope; first screening at the Novelty Theatre, Lahore on 1 January 1897
Pantopticon; first screening at the Majestic Cinema, Bombay on 14 March 1931

Correct Answer Logic:

The Lumière Brothers are the pioneers of commercial cinema projection:

The Cinématographe (1895) was their patented projection device, used for the world's first public film screening at the Grand Café, Paris in December 1895
They brought their films to India and held a premiere at the Watson Hotel, Bombay on 7 July 1896
The programme included 6 short films: Entry of cinematograph, Arrival of the train, The sea bath, A demolition, Leaving the factory, and Ladies and Soldiers on wheels
From 18 July 1896, films were screened at the Novelty Theatre on a regular basis

Note: The Kinetoscope was Thomas Edison's peepshow device for individual viewing (1893), not a projection device. The Vitascope was a U.S. projection machine first used in New York in 1896. The distinction between a peepshow viewer (one person at a time) and a projection device (audience) is critical to cinema history.

Chemistry QUESTION #5537

Question 3796

If the activation energy of a reaction is $80.9\ \text{kJ mol}^{-1}$, the fraction of molecules at 700 K having sufficient energy to react is $e^{-x}$. Find the value of $x$ (nearest integer). [Use $R = 8.31\ \text{J K}^{-1}\text{mol}^{-1}$]

14✔️
13
12
11

Correct Answer Logic:

The fraction of molecules with energy $\geq E_a$ is given by $f = e^{-E_a/RT}$. So $x = \frac{E_a}{RT} = \frac{80900}{8.31\times700} = \frac{80900}{5817} \approx 13.9 \approx 14$.

Yes, under the 'Perfect Tender Rule'.
No, unless the delay substantially impairs the value of the whole contract.✔️
Yes, but only if the Buyer is a non-merchant.
