Question 2582
A 220 kV transmission line has surge impedance $Z_c = 250\,\Omega$. The Surge Impedance Loading (SIL) is:
Correct Answer Logic:
$\text{SIL} = \frac{V_R^2}{Z_c} = \frac{(220 \times 10^3)^2}{250} = \frac{4.84 \times 10^{10}}{250} = 193.6\,\text{MW}$.

Drought escape as a mechanism of crop adaptation to water deficit differs from drought tolerance in that:
Correct Answer Logic:
Drought adaptation mechanisms: Escape (phenological โ early maturity, photoperiod sensitivity completes grain fill before drought); Avoidance (reducing water loss: deep roots, stomatal closure, leaf rolling, reduced leaf area); Tolerance (maintaining function at low tissue water potential: osmotic adjustment, desiccation tolerance). Escape is a timing strategy, not a physiological response to stress.

(Select the best word. Note: two words produce sentences alike in meaning โ choose the most accurate.)

'Momentary' would also work (these two are the synonym pair in the original). 'Complete' is the opposite of what's implied. 'Premature' means too early, not temporary. 'Trivial' means insignificant, not temporary.

Question 2599
If the length of a conductor is made 4 times its original length, its resistance becomes:
Correct Answer Logic:
Resistance $R = \dfrac{\rho L}{A}$. Since $R \propto L$ (at constant cross-sectional area and resistivity), if $L$ becomes $4L$, then $R$ becomes $4R$. The resistance becomes $\mathbf{4}$ times the original.
