Islamic Studies QUESTION #8225

Two months of Islamic Calender
Two kinds of Tax in Islam✔️
Two prominent warriors of Islam
None of these

Correct Answer Logic:

Ushr and Khums are two types of Islamic taxes. Ushr is a 10% (or 5% if irrigated) agricultural tax on produce from land. Khums literally means 'one-fifth' and is a 20% tax on war booty, treasure troves, and certain types of income. These Islamic fiscal policies ensure wealth distribution and support the state treasury (Bayt al-Mal) to help the poor and fund public welfare.

Question 2

Who is associated with the concept of fluid intelligence and crystallized intelligence?

Jean Piaget
Raymond Cattell✔️
Charles Spearman
Howard Gardner

Correct Answer Logic:

Raymond Cattell (and later John Horn) proposed the distinction between fluid intelligence (Gf) — the ability to reason and solve novel problems, independent of acquired knowledge — and crystallized intelligence (Gc) — accumulated knowledge and skills from experience and education. This distinction is central to the Cattell-Horn-Carroll (CHC) theory of cognitive abilities.

Mathematics QUESTION #1259

Question 3

Are the vectors \(\mathbf{a}=(1,2,3)\), \(\mathbf{b}=(2,5,7)\), \(\mathbf{c}=(1,3,5)\) linearly dependent or independent?

Linearly independent
Linearly dependent✔️
Cannot be determined
Orthogonal

Correct Answer Logic:

Form the matrix and compute the determinant: \(\begin{vmatrix}1&2&3\\2&5&7\\1&3&5\end{vmatrix} = 1(25-21)-2(10-7)+3(6-5) = 4-6+3=1 \neq 0\). Wait: \(= 1(25-21)-2(10-7)+3(6-5)=4-6+3=1\). Det\(\neq 0\) means linearly independent. Actually recomputing: \(5\times5-7\times3=25-21=4\); \(2\times5-7\times1=10-7=3\); \(2\times3-5\times1=6-5=1\). Det\(=1(4)-2(3)+3(1)=4-6+3=1\neq0\). Linearly independent.

Agronomy QUESTION #2066

Question 7

The response of crops to micronutrient application follows which relationship, making diagnosis and management more complex than macronutrients?

A linear response with no upper toxicity threshold
A Mitscherlich-type diminishing returns curve identical to macronutrients
A 'Piper-Steenbjerg effect' or Gaussian curve — deficiency at low concentrations, optimum growth at adequate supply, and toxicity (reduced growth) at high concentrations — with a very narrow sufficiency range✔️
A step function where deficiency disappears immediately at the critical concentration

Correct Answer Logic:

Micronutrient response follows a bell-shaped or Gaussian curve: deficiency → optimum → toxicity over a narrow concentration range. This is particularly pronounced for B, Mn, Cu, and Mo. The narrow window between deficiency and toxicity makes micronutrient management far more precise and challenging than macronutrient management.

Question 13

The principle of angular impulse and momentum about a fixed point O states:

Angular momentum equals linear momentum times radius
\(\mathbf{H}_{O2} - \mathbf{H}_{O1} = \int_{t_1}^{t_2}\sum\mathbf{M}_O\,dt\)✔️
Torque equals moment of inertia
Angular momentum is always conserved

Correct Answer Logic:

The angular impulse-momentum principle: \(\mathbf{H}_{O2}=\mathbf{H}_{O1}+\int_{t_1}^{t_2}\sum\mathbf{M}_O\,dt\), where \(\mathbf{H}_O=\mathbf{r}\times m\mathbf{v}\) is angular momentum.

Question 16

The Case Fatality Rate (CFR) of a disease is best described as:

The number of deaths per 1,000 population
The proportion of diagnosed cases that die from the disease✔️
The probability of dying in a given year
The number of deaths per 100,000 live births

Correct Answer Logic:

The Case Fatality Rate (CFR) measures the severity of a disease:

\\text{CFR} = \\frac{\\text{Number of deaths due to disease}}{\\text{Number of confirmed cases of disease}} \\times 100

It is expressed as a percentage. A high CFR indicates a more lethal disease. For example, during the COVID-19 pandemic, CFR was closely monitored to assess disease severity. CFR differs from mortality rate, which uses total population as the denominator.

Question 18

Which concept in social psychology refers to the tendency for individuals to exert less effort on a collective task when working in a group than when working alone, due to reduced personal accountability?

Social facilitation
Deindividuation
Social loafing✔️
Bystander effect

Correct Answer Logic:

Social loafing, identified by Max Ringelmann and later studied by Latané, Williams, and Harkins, is the reduction of individual effort when working collectively. People tend to 'free-ride' in groups because their individual contributions are less identifiable. Social loafing is more common in larger groups and can be reduced by making individual contributions identifiable and emphasizing personal responsibility.
