Agronomy QUESTION #2074

In the context of water use efficiency (WUE), deficit irrigation strategy is agronomically justified when:

Full irrigation always maximizes both yield and profit regardless of water scarcity
Marginal value of the last unit of water applied to the crop (in terms of yield gain) falls below the marginal cost of water supply — intentionally applying less than full ET requirement increases WUE and economic returns per unit water while accepting a modest, manageable yield reduction✔️
Water is abundant and energy costs are negligible
Soil salinity prevents full water application

Correct Answer Logic:

Deficit irrigation deliberately applies water below full ET demand during less sensitive growth stages, exploiting crop drought tolerance to save water. The agronomic justification is economic: when water is scarce or costly, WUE (kg yield per m³ water) and profit per unit water is maximized by deficit irrigation — even with modest yield reduction — compared to fully irrigating a smaller area.

Physics QUESTION #1000

Question 1025

For a diatomic gas, $\gamma_1 = \left(\dfrac{C_p}{C_v}\right)$ for rigid molecules and $\gamma_2 = \left(\dfrac{C_p}{C_v}\right)$ for non-rigid diatomic molecules (with vibrational modes). Then which is correct?

$\gamma_2 = \gamma_1$
$2\gamma_2 = \gamma_1$
$\gamma_2 < \gamma_1$✔️
$\gamma_2 > \gamma_1$

Correct Answer Logic:

For rigid diatomic: $C_v = \frac{5}{2}R$, $\gamma_1 = \frac{7}{5} = 1.4$. With vibrational modes: $C_v = \frac{7}{2}R$, $\gamma_2 = \frac{9}{7} \approx 1.286$. Since adding vibrational modes increases $C_v$ more than $C_p$, $\gamma_2 < \gamma_1$.

Aptitude QUESTION #4084

Question 1027

A librarian is organizing a special display on a narrow shelf that has exactly 5 slots. She must select books from the following collection:

5 unique Physics books
4 unique Mathematics books

The display must follow these strict rules:

Exactly 3 Physics books and 2 Mathematics books must be chosen.
The Mathematics books must never be placed next to each other.
A specific Physics book (P1) is a "must-have" and must always be included in the selection.

The total number of possible arrangements for this display is:

A) B) C) D)

Less than 400
At least 400 but less than 800
At least 800 but less than 1200
1200 or more✔️

Correct Answer Logic:

To solve this, you have to break it down into the same "Select then Arrange" flow:

Selection ( $C$ ): * We need 3 Physics books. Since P1 is mandatory, we only need to choose 2 more from the remaining 4. Calculation: $\binom{4}{2} = 6$ .
- We need 2 Math books from 4. Calculation: $\binom{4}{2} = 6$ .
- Total selection combinations: $6 \times 6 = 36$ .
Arrangement ( $P$ ): * We have 5 books (3 Physics, 2 Math).
- The "Gap Method" is best for the constraint "Math books not together."
- First, arrange the 3 Physics books: $3! = 6$ ways.
- This creates 4 possible gaps ( _ P _ P _ P _ ).
- We must place the 2 Math books into these 4 gaps: $^4P_2 = 12$ ways.
- Total arrangements per selection: $6 \times 12 = 72$ .
Final Calculation:
- $36 \text{ (selections)} \times 72 \text{ (arrangements)} = 2592$ .

Correct Answer: D (1200 or more)

Chemistry QUESTION #1424

Question 1028

In gas chromatography, the mobile phase is:

Liquid
Gas✔️
Solid
None of these

Correct Answer Logic:

In gas chromatography (GC), the mobile phase is an inert carrier gas — typically helium, nitrogen, or hydrogen. The sample components partition between this gaseous mobile phase and the stationary phase (a liquid or solid coated on the column). In liquid chromatography (HPLC), the mobile phase is a liquid, and in thin-layer chromatography, it is a liquid solvent.

Question 1038

A proposal has been made to trim the horns from rhinoceroses to discourage poachers; the question is _____ rhinoceroses after their horns are trimmed.

whether tourists will continue to visit game parks and see rhinoceroses after their horns are
whether tourists will continue to visit game parks to see one once their horns are
whether tourists will continue to visit game parks to see rhinoceroses once the animals' horns have been✔️
if tourists will continue to visit game parks and see rhinoceroses once the animals' horns are

Correct Answer Logic:

Whether' (not 'if') is proper in indirect questions. 'The animals' horns' eliminates the ambiguous pronoun 'their' (whose horns — tourists' or rhinoceroses'?). 'To see rhinoceroses' (infinitive of purpose) is more precise than 'and see.' Options D and E incorrectly use 'if.' Options A and B retain ambiguous 'their.'
