Journalism / Mass Communication QUESTION #6422

Question 3

The concept of 'noise' in communication as defined in Shannon's model has three distinct types. Which of the following CORRECTLY identifies all three types of noise as mentioned in the textbook?

Visual noise, Audio noise, and Tactile noise
Physical (mechanical/engineering) noise in the channel; Semantic noise arising from differences in meaning and experience; and Psychological noise arising from the encoding and decoding process✔️
Technical noise, Cultural noise, and Linguistic noise
Primary noise, Secondary noise, and Tertiary noise

Correct Answer Logic:

The textbook discusses noise in the Shannon-Weaver model context and identifies three categories:

Physical (Mechanical/Engineering) Noise: Unexplained variation or random error in the communication channel. Examples: a loud motorbike during conversation, smudges on a printed page, “snow” on a TV set, mist on a car windscreen, a crackling microphone. Shannon was primarily concerned with this type.
Semantic Noise: Arises from differences in meaning — when sender and receiver do not share the same knowledge, cultural background, experience, attitudes, beliefs, or linguistic skills. This is “the very essence of the study of human communication.”
Psychological Noise: The textbook mentions “psychological interference with encoding and decoding” — arising from emotional states, biases, prejudices, or mental conditions that distort how messages are encoded or decoded.

Channel overload — when the channel capacity is exceeded — is also mentioned as a source of distortion distinct from noise per se.

Agronomy QUESTION #2055

Question 6

The permanent wilting point (PWP) of soil is the moisture content at which:

All gravitational water has drained from the soil macropores
Plants can no longer extract sufficient water from the soil and wilt permanently, corresponding to a soil matric potential of approximately $-1500$ kPa (or $-15$ bar)✔️
Soil moisture equals 50% of field capacity
Surface evaporation exceeds plant transpiration

Correct Answer Logic:

PWP is the soil moisture content at which the remaining water is held so tightly by soil particles (matric potential ≈ −1500 kPa) that roots cannot exert sufficient suction to extract it. Plants wilt permanently — they do not recover even when placed in a humid atmosphere. Plant-available water = FC − PWP.

Question 8

According to Section 2(a), an 'ad hoc appointment' is defined as appointment of a duly qualified person made otherwise than in accordance with the prescribed method of recruitment, pending what?

Completion of probation period
Recruitment in accordance with such method✔️
Approval of the Federal Public Service Commission
Issuance of a formal notification by the President

Correct Answer Logic:

Section 2(a) defines an ad hoc appointment as the appointment of a duly qualified person made otherwise than in accordance with the prescribed method of recruitment, pending recruitment in accordance with such method. It is thus a temporary arrangement until regular recruitment is completed.

Physics QUESTION #4408

Question 10

The curved shape of an airplane wing causes air to move faster over the top surface. This leads to:

Greater pressure on the top
Lower pressure on the top✔️
Equal pressure on both sides
Zero pressure above the wing

Correct Answer Logic:

By Bernoulli's principle, faster-moving air exerts lower pressure. Air moves faster over the curved upper surface of the wing, creating lower pressure above and higher pressure below, generating lift ($\Delta P = \frac{1}{2}\rho v^2$).

Question 12

If $\varphi: \mathbb{Z}_{12} \to \mathbb{Z}_{18}$ is a group homomorphism, how many exist?

$6$
$4$
$12$
$\gcd(12, 18) = 6$✔️

Correct Answer Logic:

Number of homomorphisms from $\mathbb{Z}_m$ to $\mathbb{Z}_n$ equals $\gcd(m, n) = \gcd(12, 18) = 6$.

Question 16

Match the physical quantities in List I with their correct dimensional formulas in List II:

List I	List II
(A) Spring constant	(1) $M^1L^2T^{-2}$
(B) Pascal (unit of pressure)	(2) $M^0L^0T^{-1}$
(C) Hertz (unit of frequency)	(3) $M^1L^0T^{-2}$
(D) Joule (unit of energy)	(4) $M^1L^{-1}T^{-2}$

Choose the correct matching:

A-3, B-4, C-2, D-1
A-4, B-3, C-1, D-2
A-4, B-3, C-2, D-1✔️
A-3, B-4, C-1, D-2

Correct Answer Logic:

Spring constant $k$: $F = kx \Rightarrow [k] = \frac{[F]}{[x]} = \frac{MLT^{-2}}{L} = MT^{-2} = M^1L^0T^{-2}$ → (3)
Pascal (pressure): $[P] = \frac{Force}{Area} = \frac{MLT^{-2}}{L^2} = ML^{-1}T^{-2} = M^1L^{-1}T^{-2}$ → (4)
Hertz (frequency): $[f] = T^{-1} = M^0L^0T^{-1}$ → (2)
Joule (energy): $[E] = ML^2T^{-2} = M^1L^2T^{-2}$ → (1)

Correct match: A-3, B-4, C-2, D-1

Education QUESTION #6770

Question 18

In developing MCQ distractors, a teacher writes: 'Which country first used nuclear weapons in warfare? a) USA b) Soviet Union c) Germany d) France'. Only option (a) is a genuine threat to an informed student. What principle of MCQ construction is violated?

The stem should not use negative phrasing
Distractors should be plausible to uniformed students; implausible distractors do not contribute to item functioning and should be revised✔️
The stem should present a definite problem
All options should be grammatically consistent with the stem

Correct Answer Logic:

A core rule of MCQ construction is that all distractors must be plausible to students who lack the relevant knowledge. If a distractor is not selected by any student in a field test, it contributes nothing to the item's measurement function and should be replaced with a more compelling incorrect option.

Question 19

When implementing project-based learning, assessment should PRIMARILY focus on:

Only final product quality
Both process and product using multiple assessment methods✔️
Teacher perception only
Peer popularity of project

Correct Answer Logic:

Project-based learning assessment should evaluate both process (research, collaboration, problem-solving) and product (final outcome quality) using rubrics, portfolios, presentations, and reflection. Comprehensive assessment captures multiple dimensions of learning.

Law QUESTION #9495

Question 20

A plaintiff institutes a suit for recovery of a loan on the basis of a promissory note. The defendant files a written statement but does not raise the defence of limitation. The Court frames issues but the defendant never raises limitation at trial. Can the Court, on its own motion, dismiss the suit on the ground that it is time-barred?

Yes; under the Limitation Act, every suit filed after the prescribed period is barred, and the Court must dismiss it regardless of whether it is pleaded, if the suit is apparently time-barred on the face of the plaint✔️
Yes; but only in appeals
No; limitation must be specifically pleaded by the defendant and the Court cannot raise it suo motu
No; a Court can only act on issues that are framed

Correct Answer Logic:

Section 3 of the Limitation Act 1908 imposes a mandatory obligation on every Court to dismiss a suit, appeal, or application that is prima facie time-barred, even if limitation has not been pleaded as a defence. The Court acts suo motu in such cases.
