Question 3

A number of linguists contend _____ can be traced back to a common root language.

that all of the thousands of languages spoken by the world's five billion people can be traced✔️
that the world's five billion people speak thousands of languages of which all can be traced
the world's five billion people speak thousands of languages which are all traceable
all of the thousands of languages spoken by the world's five billion people to be traceable

Correct Answer Logic:

Contend that…can be traced' is the proper construction after a verb of assertion. Option D omits 'that' and uses an awkward infinitive. Option E turns the contention into an ability claim. Options B and C shift the focus unnecessarily from the languages to the speakers.

Physics QUESTION #1040

Question 4

A container with $V_1=2\ \text{L},\ n_1=5\ \text{mol},\ p_1=1\ \text{atm}$ and $V_2=3\ \text{L},\ n_2=4\ \text{mol},\ p_2=2\ \text{atm}$ is separated by a thermal insulator. When partition is removed, equilibrium pressure is:

1.4 atm
1.8 atm
1.3 atm
1.6 atm✔️

Correct Answer Logic:

Since the partition is a thermal insulator, after mixing the total internal energy is conserved. For ideal gas: $U \propto nT$. From ideal gas law: $T_1=\frac{p_1V_1}{n_1R}=\frac{1\times2}{5R}=\frac{2}{5R}$ and $T_2=\frac{2\times3}{4R}=\frac{6}{4R}$. Final $T_f = \frac{n_1T_1+n_2T_2}{n_1+n_2}=\frac{5\cdot\frac{2}{5R}+4\cdot\frac{6}{4R}}{9}=\frac{\frac{2}{R}+\frac{6}{R}}{9}=\frac{8}{9R}$. Final $p=\frac{(n_1+n_2)RT_f}{V_1+V_2}=\frac{9R\cdot\frac{8}{9R}}{5}=\frac{8}{5}=1.6\ \text{atm}$.

Physics QUESTION #7016

Question 5

A hoop with radius $r$ and mass $m$ is rotating with an initial angular velocity $\omega_0$ and is placed on a rough horizontal floor. If the initial linear velocity of its center is zero, what will be the final linear velocity of the center when the hoop stops slipping and begins pure rolling?

$\frac{r\omega_0}{4}$
$\frac{r\omega_0}{3}$
$\frac{r\omega_0}{2}$✔️
$r\omega_0$

Correct Answer Logic:

Using the principle of conservation of angular momentum about the point of contact: $L_i = L_f$. Initial angular momentum $L_i = I \omega_0 = (mr^2) \omega_0$. Final angular momentum $L_f = I \omega + mrv = (mr^2)(\frac{v}{r}) + mrv = 2mrv$. Equating $mr^2\omega_0 = 2mrv$ gives $v = \frac{r\omega_0}{2}$.

Contracts QUESTION #5839

Question 8

A Retailer and a Wholesaler enter into an oral agreement for the sale of $1,000$ units of a specific electronic component at a price of $0.75$ per unit. The Wholesaler sends a signed written confirmation to the Retailer the next day stating: 'This confirms our deal for $1,000$ units at $0.75$ each.' The Retailer receives the note but objects 12 days later. Is the contract enforceable?

No, because it was not signed by the Retailer.
Yes, because the Retailer failed to object within 10 days of receipt.✔️
No, because oral contracts for goods are never enforceable.
Yes, because the total value is under $1,000$.

Correct Answer Logic:

Under UCC §2-201(2), the Merchant's Confirmatory Memo rule binds the recipient if they fail to object in writing within 10 days.

Question 9

A firm that specializes in the analysis of handwriting claims _____ more than three hundred personality traits, including enthusiasm, imagination, and ambition.

from a one-page writing sample that it can assess
from a one-page writing sample it has the ability of assessing
the ability, from a one-page writing sample, of assessing
to be able, from a one-page writing sample, to assess✔️

Correct Answer Logic:

Claims to be able…to assess' is the proper idiomatic construction. Option A misplaces the modifier 'from a one-page writing sample' before the 'that' clause. Options B and C use non-idiomatic constructions. Option E would produce a dangling participial phrase.

Sociology QUESTION #1668

Question 10

C. Wright Mills argued in his 1956 work that democratic governance in the United States was effectively superseded by the coordinated dominance of a small, interconnected elite drawn from corporate, military, and political institutions. The concept he developed to describe this concentration of power is:

The Iron Law of Oligarchy
The Power Elite✔️
The Ruling Class
The Military-Industrial Complex

Correct Answer Logic:

In 'The Power Elite' (1956), C. Wright Mills argued that real power in the United States is held by a small group of men who occupy the command posts of the major institutional hierarchies — large corporations, the military, and the executive branch of government — whose interests are intertwined and who make the most consequential decisions affecting society.

Question 12

Under Rule 5(10) if a Secretary believes a Minister's decision is manifestly wrong and the Minister still adheres to it what is the next step?

The Secretary shall implement the decision under protest
The Secretary shall refer the case to the Cabinet
The Secretary shall request the Minister to refer the case to the Prime Minister and if not referred shall submit it directly to the Prime Minister with the Minister's observations✔️
The Secretary shall resign from office

Correct Answer Logic:

Rule 5(10) prescribes a specific escalation: the Secretary re-submits stating reasons; if Minister still adheres the Secretary requests referral to PM; if the case is not referred the Secretary submits it directly to the Prime Minister with the Minister-in-Charge's observations.

Mathematics QUESTION #6031

Question 14

Let $f(x)=\begin{cases}\max\{|x|,x^2\},&|x|\le2\\8-2|x|,&2<|x|\le4\end{cases}$. Let $S$ be the set of points in $(-4,4)$ where $f$ is not differentiable. Find $S$.

Empty set
$\{-2,-1,0,1,2\}$✔️
$\{-2,-1,1,2\}$
$\{-2,2\}$

Correct Answer Logic:

On $[-2,2]$: $\max(|x|,x^2)=x^2$ when $x^2\ge|x|$, i.e., $|x|\ge1$; equals $|x|$ when $|x|\le1$.

So $f(x)=|x|$ for $|x|\le1$ and $f(x)=x^2$ for $1\le|x|\le2$.

Check non-differentiability: At $x=0$: $|x|$ is not differentiable. At $x=\pm1$: left-hand $f'=\pm1$, right-hand $f'=2x=\pm2$ — not equal, so not differentiable. At $x=\pm2$: $f(2^-)=4$, $f(2^+)=4$; $f'(2^-)=4$, $f'(2^+)=-2$ — not differentiable.

So $S=\{-2,-1,0,1,2\}$.

Question 17

The dimensional formula of magnetic field $B$ is:

$M^1L^2T^{-3}A^{-1}$
$M^1L^{-1}T^{-2}A^{-1}$
$M^1L^0T^{-2}A^{-1}$✔️
$M^1L^1T^{-2}A^{-1}$

Correct Answer Logic:

From Lorentz force: $F = qvB$

$[B] = \dfrac{[F]}{[q][v]} = \dfrac{MLT^{-2}}{AT \cdot LT^{-1}} = \dfrac{MLT^{-2}}{AL} = MT^{-2}A^{-1} = M^1L^0T^{-2}A^{-1}$
