Ability / HR / Governance / Special Education QUESTION #5637

Under the budgetary procedure a Ministry proposes a lump-sum provision in its Current Expenditure budget for an item not yet fully specified. What principle does this violate and what is the correct course?

It violates the Prudence principle; the item should be deferred to the next year
Lump-sum provisions in Current Expenditure are prohibited except in exceptional circumstances and must require the concurrence of the Financial Adviser when made✔️
It violates the Purpose principle; the item should be separately itemized without Financial Adviser involvement
It is acceptable practice as long as PAO certifies the amount

Correct Answer Logic:

Lump-sum provision in the budget shall not be proposed or made except in exceptional circumstances (such as lump provision for late NIS late receipt of directives). Where such provision is made expenditure sanction shall be given with the concurrence of the Financial Adviser.

A subject-specific encyclopaedia
A general encyclopaedia✔️

Question 3386

The theories which explain the formation of sigma ($\sigma$) and pi ($\pi$) bonds are EXCEPT:

MOT
VBT
VSEPR
CFT✔️

Correct Answer Logic:

Valence Bond Theory (VBT) explains $\sigma$ and $\pi$ bond formation through orbital overlap. Molecular Orbital Theory (MOT) also describes bonding. VSEPR predicts shape. Crystal Field Theory (CFT) deals with d-orbital splitting in coordination complexes — it does NOT explain $\sigma$ and $\pi$ bond formation.

Statistics QUESTION #1978

Question 3388

Given $n_1 = 2$ samples with replacement from population $\{4, 6, 8\}$ and $n_2 = 2$ from $\{1, 2, 3\}$, the variance of the sampling distribution of $\bar{X}_1 - \bar{X}_2$ equals:

$\dfrac{\sigma_1^2}{n_1} - \dfrac{\sigma_2^2}{n_2}$
$\dfrac{\sigma_1^2}{n_1} + \dfrac{\sigma_2^2}{n_2}$✔️
$\sigma_1^2 + \sigma_2^2$
$\dfrac{\sigma_1^2 + \sigma_2^2}{n_1 + n_2}$

Correct Answer Logic:

For independent samples, $\sigma^2_{\bar{X}_1 - \bar{X}_2} = \dfrac{\sigma_1^2}{n_1} + \dfrac{\sigma_2^2}{n_2}$. For population $\{4,6,8\}$: $\mu_1=6$, $\sigma_1^2 = \frac{8}{3}$. For $\{1,2,3\}$: $\mu_2=2$, $\sigma_2^2=\frac{2}{3}$. So variance $= \frac{8/3}{2}+\frac{2/3}{2} = \frac{4}{3}+\frac{1}{3}=\frac{5}{3}$.

Question 3395

A power series solution $y=\sum_{n=0}^\infty a_n x^n$ to an ODE converges in a neighbourhood of an ordinary point $x_0$ up to the distance to the nearest:

Irregular singular point
Singular point✔️
Ordinary point
Boundary point

Correct Answer Logic:

By the theorem on power series solutions, if $x_0$ is an ordinary point of the ODE, the power series solution converges in the interval \(|x-x_0|

Physics QUESTION #4410

Question 3396

Mechanical waves cannot travel through outer space because they:

Have low speed in vacuum
Disperse in space due to long wavelength
Lose frequency in the absence of air
Lose transmission without interacting particles✔️

Correct Answer Logic:

Mechanical waves (sound, seismic waves) require a material medium (particles) to propagate — they transfer energy through the vibration of particles. In outer space (vacuum), there are no particles to interact with, so mechanical waves cannot travel.

Chemistry QUESTION #1101

Question 3399

The correct order of wavelength of light absorbed by complexes A. [Co(NH$_3$)$_6$]$^{3+}$ B. [Co(CN)$_6$]$^{3-}$ C. [Cu(H$_2$O)$_4$]$^{2+}$ D. [Ti(H$_2$O)$_6$]$^{3+}$:

$C < D < A < B$
$C < A < D < B$✔️
$B < D < A < C$
$B < A < D < C$

Correct Answer Logic:

Wavelength $\propto 1/\Delta_o$ (crystal field splitting). Stronger field ligands → larger $\Delta_o$ → shorter wavelength absorbed. Ligand field strength: CN$^-$ $>$ NH$_3$ $>$ H$_2$O. Also Co$^{3+}$ has larger $\Delta_o$ than Cu$^{2+}$ or Ti$^{3+}$. [Co(CN)$_6$]$^{3-}$: highest $\Delta_o$ → shortest $\lambda$. [Co(NH$_3$)$_6$]$^{3+}$ $>$ [Ti(H$_2$O)$_6$]$^{3+}$ $>$ [Cu(H$_2$O)$_4$]$^{2+}$. Order of $\lambda$: C $>$ D $>$ A $>$ B, so increasing: B $<$ A $<$ D $<$ C = option (2) C$<$A$<$D$<$B is wrong. Correct: B$<$A$<$D$<$C = option (4).
