Question 11382

A progressive tax system is one where:

Marginal tax rates are high
Higher income taxpayers pay more taxes than do lower income taxpayers.
Marginal tax rates are low.
Higher income taxpayers pay a greater percentage of their income in taxes than do lower income taxpayers.✔️

Correct Answer Logic:

A progressive tax system is one where the tax rate increases as taxable income increases — higher earners pay a larger percentage (not just a larger amount) of their income in taxes. Option (B) is also partially true but less precise; any tax (even flat) means higher earners pay more in absolute terms. Option (D) is the precise definition of a progressive system.

Civil Engineering QUESTION #6572

Question 11383

Alloys containing more than $2.1\%$ carbon by weight are classified as:

Steel
Cast Iron✔️
Pig Iron
Wrought Iron

Correct Answer Logic:

Carbon content defines the iron–carbon alloy type:

Steel: $0.008\% - 2.1\%$ C
Cast Iron: $> 2.1\%$ C (typically $2.1\% - 4\%$)

Cast iron is brittle and has high compressive strength.

Physics QUESTION #7322

Question 11386

Two cars P and Q start simultaneously from the same point. Their positions are $x_P(t) = at + bt^2$ and $x_Q(t) = ft - t^2$. At what time do they have equal velocities?

$\dfrac{a+f}{2(1+b)}$
$\dfrac{f-a}{2(1+b)}$✔️
$\dfrac{a-f}{1+b}$
$\dfrac{a+f}{2(b-1)}$

Correct Answer Logic:

$v_P = a + 2bt$, $\quad v_Q = f - 2t$

Setting equal: $a + 2bt = f - 2t \Rightarrow 2t(b+1) = f-a \Rightarrow t = \mathbf{\dfrac{f-a}{2(1+b)}}$

Accounting & Finance QUESTION #1206

Question 11388

Over-applied overhead means:

Actual overheads are less than applied overheads.✔️
Actual overheads are greater than applied overheads.
Fixed costs were not allocated properly.
Direct labor costs were overstated.

Correct Answer Logic:

Overhead is applied to production using a predetermined rate. Over-applied overhead occurs when the applied overhead (predetermined rate × actual activity) exceeds the actual overhead incurred. In other words, actual overheads < applied overheads. This means production was charged more overhead than was actually spent.

Question 11389

Trisomy of which chromosome leads to Patau's syndrome?

13th chromosome✔️
18th chromosome
21st chromosome
22nd chromosome

Correct Answer Logic:

Patau's syndrome (Trisomy 13) results from the presence of three copies of chromosome 13 ($2n + 1 = 47, +13$). It causes severe intellectual disability, cleft lip/palate, polydactyly, heart defects, and neural tube defects. Median survival is less than one week; 90% of affected infants die within the first year. Trisomy 18 = Edwards syndrome; Trisomy 21 = Down syndrome; Trisomy 22 = cat-eye syndrome or Emanuel syndrome.

Civil Engineering QUESTION #6612

Question 11390

In the design of base plates for columns, the 'equivalent cantilever' length $l$ is used to determine the plate thickness. This length is usually calculated from:

The distance from the column face to the edge of the base plate✔️
The distance between the anchor bolts
The total length of the base plate
The radius of gyration of the column

Correct Answer Logic:

Base plate thickness is determined by treating the portions of the plate extending beyond the column profile as cantilever beams loaded by the bearing pressure from the concrete foundation.

Question 11392

In Le Corbusier's Radiant City concept, what was the recommended minimum distance between high-rise buildings?

Equal to building height
Twice the building height
Three times the building height✔️
Five times the building height

Correct Answer Logic:

Le Corbusier's 'towers in the park' concept recommended spacing high-rises at three times their height to ensure adequate sunlight, air circulation, and open space between buildings while achieving high densities through vertical development.

Dairy Food Science and Technology QUESTION #5972

Question 11394

The approximate pH range of fresh normal cow's milk is:

$5.5\text{–}6.0$
$6.6\text{–}6.8$✔️
$7.2\text{–}7.5$
$4.5\text{–}5.0$

Correct Answer Logic:

Fresh normal bovine milk has a $\text{pH}$ of $6.6\text{–}6.8$ (typically $6.65\text{–}6.71$). This is slightly acidic due to dissolved $\text{CO}_2$, proteins, phosphates, and citrates. Mastitic milk tends to have higher $\text{pH}$ ($>6.8\text{–}7.0$); acidic/sour milk has lower $\text{pH}$.

Psychology QUESTION #9780

Question 11395

The term 'propinquity' in social psychology refers to:

Geographical proximity
Why people affiliate with one another
Both geographical proximity and why people affiliate✔️
None of these

Correct Answer Logic:

Propinquity refers to physical proximity between individuals. Research shows proximity increases familiarity and interaction opportunities. It also helps explain affiliation — proximity promotes liking (mere exposure effect).

Chemistry QUESTION #1104

Question 11396

Match List I (Mixture) with List II (Method of Separation): A. CHCl$_3$ + C$_6$H$_5$NH$_2$ B. Crude oil C. Glycerol from spent-lye D. Aniline-water; with I. Distillation under reduced pressure II. Steam distillation III. Fractional distillation IV. Simple distillation

A-III, B-IV, C-I, D-II
A-III, B-IV, C-II, D-I
A-IV, B-III, C-I, D-II✔️
A-IV, B-III, C-II, D-I

Correct Answer Logic:

CHCl$_3$ + aniline: miscible liquids with different bp → simple distillation (IV). Crude oil: mixture of hydrocarbons → fractional distillation (III). Glycerol from spent-lye: glycerol decomposes at bp → distillation under reduced pressure (I). Aniline-water: immiscible, high bp compound → steam distillation (II). A-IV, B-III, C-I, D-II.

Aptitude QUESTION #10969

Question 11397

Which of the following statements about reinforced cement concrete (RCC) is correct?

Steel and concrete have very different thermal expansion coefficients, causing internal stress
Concrete carries tension and steel carries compression in RCC
Steel and concrete have approximately the same coefficient of thermal expansion✔️
Steel has lower compressive strength than concrete

Correct Answer Logic:

The key reason RCC works so well:

The coefficient of thermal expansion of steel ≈ \(12 \times 10^{-6}/°C\
The coefficient of thermal expansion of concrete ≈ \(10-14 \times 10^{-6}/°C\
These are approximately equal, so both expand and contract together — no internal thermal stresses develop at the bond interface. ✓

Also: In RCC, concrete carries compression and steel carries tension (opposite of option B). Steel has much higher compressive strength than concrete (option D is wrong).
