Psychology QUESTION #9913

Which of the following could be attributed to Tolman's research?

Discovery of the law of effect
The concept of cognitive map✔️
The negative effect of punishment
The role of classical conditioning in phobic disorders

Correct Answer Logic:

Tolman's most notable contribution was the cognitive map concept — demonstrated through latent learning experiments showing rats form internal mental representations of mazes, challenging pure stimulus-response behaviourism.

Accounting & Finance QUESTION #1221

Question 2

If a tax on a good is doubled, the deadweight loss from the tax:

Doubles
Stays the same
Increases by a factor of four.✔️
Could rise or fall

Correct Answer Logic:

Deadweight loss from a tax is proportional to the square of the tax rate: $\text{DWL} \propto t^2$. If the tax doubles ($t \to 2t$), then $\text{DWL} \propto (2t)^2 = 4t^2$. So the deadweight loss increases by a factor of four. This is why large taxes are disproportionately inefficient.

Journalism / Mass Communication QUESTION #6421

Question 6

In the context of photography's role in journalism, who was the founder of the first successful photography-based photo-agency and when did Life magazine (a major vehicle for photojournalism) begin publication?

Mathew Brady founded the agency in 1850; Life magazine began in 1920
George Eastman founded it in 1888; Life magazine began in 1925
Life magazine (begun 1936) along with Look (begun 1937) provided the primary outlets for documentary photojournalism; Henri Cartier-Bresson is often credited with founding the modern photo-agency model✔️
Walker Evans and the Farm Security Administration created the first formal photojournalism programme; Life magazine was established in 1950

Correct Answer Logic:

The textbook is specific about Life magazine (begun 1936) and Look magazine (begun 1937) as the large-circulation picture magazines that “provided an outlet and a vast audience for documentary work.” The Great Depression of the 1930s provided the subject matter: the Farm Security Administration (FSA) under Roy Stryker commissioned photographers including Walker Evans, Arthur Rothstein, Russell Lee, and Dorothea Lange to document Depression-era America. World War II further developed photojournalism — photographers including Margaret Bourke-White, Robert Capa, W. Eugene Smith, and Edward Steichen documented the global conflict. The development of the 35mm “candid” camera by Oskar Barnack (Leica, first marketed 1925) made documentary photographers “infinitely more mobile and less conspicuous.” Colour film for transparencies was introduced in 1935; the Polaroid Land camera in 1947.

Economics QUESTION #1717

Question 7

The Enhanced Partnership with Pakistan Act of 2009 — commonly known as the Kerry-Lugar-Berman (KLB) Act — was a major US civilian assistance legislation that allocated USD 7.5 billion over five years primarily for which stated developmental purpose?

Strengthening Pakistan's military capacity and counterterrorism infrastructure
Financing civilian infrastructure and social sector development — particularly energy, education, and governance✔️
Expanding Pakistan's export-oriented manufacturing base and trade facilitation capacity
None of these

Correct Answer Logic:

The Kerry-Lugar-Berman Act (Enhanced Partnership with Pakistan Act, 2009) authorised USD 1.5 billion annually for five years in non-military civilian assistance to Pakistan. Its stated objectives were to support Pakistan's democratic governance, civilian institutions, and socioeconomic development — with specific focus on energy infrastructure (to address the power crisis), education (school construction and teacher training), and economic growth. It explicitly conditioned aid on civilian oversight of the military.

Education QUESTION #6905

Question 10

A teacher maintains behavioral portfolios for students. According to best practices in behavioral record keeping, which of the following should a behavioral portfolio MOST appropriately contain?

Only incident reports documenting rule violations and resulting penalties
Records of behavioral progress, observation checklists, benchmarks achieved each term, and student self-evaluations✔️
Only academic grades with behavioral remarks added in teacher comments
Letters exchanged with parents documenting disciplinary conferences

Correct Answer Logic:

Behavioral portfolios serve as systematic, longitudinal records of student behavioral development. They should be holistic — including progress observations, checklists of specific behaviors, benchmark achievements, and crucially, student self-evaluations. The self-evaluation component promotes reflection and metacognitive awareness, which supports genuine behavioral change rather than mere compliance.

Physics QUESTION #1035

Question 13

Two inclined surfaces of equal length $L$ at $45°$: one rough, one smooth. A body takes 2 times longer on the rough surface. The coefficient of kinetic friction $\mu_k$ is close to:

0.5
0.75✔️
0.25
0.40

Correct Answer Logic:

On smooth: $a_s = g\sin45°$. On rough: $a_r = g(\sin45°-\mu_k\cos45°)$. Time ratio: $t_r/t_s=2$. Since $L = \frac{1}{2}at^2$: $t\propto 1/\sqrt{a}$. So $\frac{t_r}{t_s}=\sqrt{\frac{a_s}{a_r}}=2\Rightarrow \frac{a_s}{a_r}=4\Rightarrow a_r=\frac{a_s}{4}$. $g(\sin45°-\mu_k\cos45°)=\frac{g\sin45°}{4}\Rightarrow 1-\mu_k=\frac{1}{4}\Rightarrow \mu_k=0.75$.

What is the minimum column width setting supported in MS Word?

0 inches
0.5 inches✔️
1 inch

Question 16

A Ministry intends to include a new unapproved development scheme in the PSDP allocation. Under what condition is this permitted and what safeguard is required?

It is never permitted as only approved schemes may be included in PSDP
It may be included in exceptional circumstances only after anticipatory approval by the competent authority has been obtained✔️
It may be included if the Financial Adviser certifies it fits into the overall development plan
It may be included as long as the CDWP is informed within 30 days

Correct Answer Logic:

Allocation in the PSDP for new unapproved development schemes/projects shall be made in exceptional circumstances only after anticipatory approval of such new schemes/projects by the competent authority.

Civil Engineering QUESTION #6614

Question 17

A steel rod of area $A$ and length $L$ is fixed at both ends. If the temperature increases by $\Delta T$, the thermal stress induced is:

$E \alpha \Delta T$✔️
$E \alpha \Delta T / L$
$A E \alpha \Delta T$
Zero, as it is free to expand

Correct Answer Logic:

Thermal strain $\epsilon = \alpha \Delta T$. Since expansion is prevented (fixed ends), the stress is $\sigma = E \epsilon = E \alpha \Delta T$.

Mathematics QUESTION #7429

Question 18

If the lines $\frac{x-2}{1} = \frac{y-3}{1} = \frac{z-4}{-k}$ and $\frac{x-1}{k} = \frac{y-4}{2} = \frac{z-5}{1}$ are coplanar, then k can have:

any value
exactly one value
exactly two values✔️
exactly three values

Correct Answer Logic:

For two lines to be coplanar, the scalar triple product of their direction ratios and the vector joining points on the lines must be zero. The direction ratios are $(1, 1, -k)$ and $(k, 2, 1)$. A point on the first line is $(2, 3, 4)$ and on the second is $(1, 4, 5)$. The vector joining them is $(-1, 1, 1)$. Setting up the determinant: $\begin{vmatrix} -1 & 1 & 1 \\ 1 & 1 & -k \\ k & 2 & 1 \end{vmatrix} = 0$. Expanding: $-1(1+2k) - 1(1+k^2) + 1(2-k) = 0$, which simplifies to $k^2 + 3k = 0$, giving $k = 0$ or $k = -3$. Thus, k has exactly two values.

Electrical Engineering QUESTION #2179

Question 19

A lossless $50\,\Omega$ transmission line of electrical length $\lambda/4$ is terminated with $Z_L = 25\,\Omega$. The input impedance seen at the source is:

$100\,\Omega$✔️
$25\,\Omega$
$50\,\Omega$
$12.5\,\Omega$

Correct Answer Logic:

Quarter-wave transformer property: $Z_{in} = \frac{Z_0^2}{Z_L} = \frac{(50)^2}{25} = \frac{2500}{25} = 100\,\Omega$.
