Reading and Writing (Module-1) QUESTION #5434

Question 4965

In Mansfield's "The Young Girl," the narrator describes a 17-year-old. Mansfield contrasts pleasant appearance with unpleasant attitude. Which quotation best illustrates this contrast?

"I heard her murmur, 'I can't bear flowers on a table.' They had evidently been giving her intense pain..."
"While we waited she took out a little gold powder-box... and dabbed her lovely nose."✔️
"I saw... she couldn't stand this place... she jumped up... while I went through the vulgar act of paying."
"She didn't even take her gloves off. She lowered her eyes and drummed on the table..."

Correct Answer Logic:

Dabbing her "lovely nose" (pleasant appearance) after loathing the puff (unpleasant attitude) shows contrast.

Question 4966

What is the correct accounting entry for interest on capital for partner X?

Option	Account Debited	Account Credited
A	Appropriation	X's capital account
B	Appropriation	X's current account
C	X's capital account	Appropriation
D	X's current account	Appropriation

Option A
Option B✔️
Option C
Option D

Correct Answer Logic:

Option B is correct.

Debit: Appropriation account — reduces profit available for sharing.
Credit: X's current account — increases the partner's entitlement.

Capital accounts hold fixed capital contributions. Interest on capital, drawings, and profit shares pass through the current account.

Electrical Engineering QUESTION #2160

Question 4967

A signal $x(t) = 5\cos(200\pi t) + 3\sin(400\pi t)$ is sampled at $f_s = 300\,\text{Hz}$. Which frequency component(s) experience aliasing?

Both $100\,\text{Hz}$ and $200\,\text{Hz}$✔️
$100\,\text{Hz}$ only
$200\,\text{Hz}$ only
No aliasing occurs

Correct Answer Logic:

The two components have frequencies $100\,\text{Hz}$ and $200\,\text{Hz}$. The Nyquist limit is $f_s/2 = 150\,\text{Hz}$. Since both exceed $150\,\text{Hz}$, both components alias.

Aptitude QUESTION #4084

Question 4968

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)

Constitutional Law QUESTION #5811

Question 4970

A state law requires all private and public employers to give employees a day of rest on their chosen 'Sabbath.' An employee at a large tech firm demands Sundays off. The firm fires him because Sundays are their busiest days. The employee sues under the state law. The employer argues the law violates the Establishment Clause. Is the law constitutional?

Yes, because it protects the free exercise rights of all employees.
Yes, because the law has a secular purpose of ensuring a day of rest for workers.
No, because it has the primary effect of advancing religion by giving an absolute preference to Sabbath observers.✔️
No, because it fails the 'neutrality' test by targeting only religious days of rest.

Correct Answer Logic:

In Thornton v. Caldor, the Supreme Court held that a law giving an absolute preference to Sabbath observers over all other interests violates the Establishment Clause because it lacks a secular purpose and primary effect that is neutral, essentially 'endorsing' religious practices over secular business needs.

Question 4972

What is the total number of lone pairs of electrons in the $I_3^-$ ion?

9✔️
12
3
6

Correct Answer Logic:

In $I_3^-$: Central iodine has 3 lone pairs, each terminal iodine has 3 lone pairs each. Total lone pairs = 3 (central I) + 3 (terminal I) + 3 (terminal I) = 9 lone pairs. The structure is linear with the central I having 2 bond pairs and 3 lone pairs ($sp^3d$ hybridization).

Agronomy QUESTION #2073

Question 4975

The Blaney-Criddle method of estimating crop water requirements is primarily based on:

Net solar radiation and wind speed data
Mean monthly temperature and daylight hours (sunshine percentage), making it suitable for regions where only temperature data are available but less accurate than the Penman-Monteith method✔️
Actual measured pan evaporation data corrected by a pan coefficient
Soil type and available water capacity in the root zone

Correct Answer Logic:

The Blaney-Criddle formula $ET = p(0.46T + 8)$ uses only mean monthly temperature (T) and monthly percentage of annual daylight hours (p). It was widely used before reliable radiation and humidity data were available. While simple, it overestimates ET in humid conditions and underestimates in arid climates — less accurate than the Penman-Monteith equation.
