Journalism / Mass Communication QUESTION #6354

David Berlo's SMCR Model (1960) identifies five communication skills. Two are encoding skills and two are decoding skills, with one skill common to both. Which of the following correctly identifies ALL five?

Encoding: Listening and Reading; Decoding: Speaking and Writing; Common: Reasoning
Encoding: Speaking and Writing; Decoding: Listening and Reading; Common: Thought or Reasoning✔️
Encoding: Reading and Reasoning; Decoding: Writing and Speaking; Common: Listening
Encoding: Speaking and Listening; Decoding: Reading and Writing; Common: Thinking

Correct Answer Logic:

David Berlo's SMCR (Source-Message-Channel-Receiver) Model places heavy emphasis on the communication skills of both the source/encoder and the receiver/decoder. According to Berlo:

Encoding skills (producing messages): Speaking and Writing
Decoding skills (receiving messages): Listening and Reading
Skill common to both encoding and decoding: Thought or Reasoning — the intellectual capacity to analyse intentions and translate them into appropriate language or interpret received language accurately

Berlo also stressed the dyadic (two-party, relationship-based) nature of communication: the same skill level in a source might succeed with one receiver but fail with another because the receiver's skill, knowledge, attitude, and socio-cultural background differ. This makes fidelity — the degree to which the received message matches the intended message — the key measure of communication quality.

Maths QUESTION #2817

Question 9182

A batsman's average after 12 innings is 36. In the 13th inning he scores 87. What is his new average?

39
39.5
40✔️
40.5

Correct Answer Logic:

Total runs after 12 innings $= 12 \times 36 = 432$. After 13th inning $= 432 + 87 = 519$. New average $= \dfrac{519}{13} = 39.92 \approx 40$.

Education QUESTION #11618

Question 9183

The capacity to apply acquired knowledge effectively in practical or real-world situations is best described as:

Learning
Intelligence✔️
Flexibility

Statistics QUESTION #2014

Question 9188

In testing $H_0: \beta = 0$ against $H_1: \beta \neq 0$ in simple linear regression with $n = 7$ observations, the test statistic follows a t-distribution with degrees of freedom:

5✔️
6
7
4

Correct Answer Logic:

In simple linear regression with $n$ observations, the t-test for the slope $\beta$ uses $df = n - 2$ degrees of freedom (one lost for the slope, one for the intercept). With $n = 7$, $df = 7 - 2 = 5$.

MBBS QUESTION #10221

Question 9189

Using the Nernst equation for potassium, $E_K = 61 \log_{10}\frac{[K^+]_o}{[K^+]_i}$ (mV, approx. at body temperature), a patient develops severe hyperkalemia. How does the resting membrane potential of excitable cells change, and what is the clinical consequence?

$E_K$ becomes less negative (membrane depolarizes), initially increasing excitability but ultimately causing dangerous conduction abnormalities✔️
$E_K$ becomes more negative (membrane hyperpolarizes), reducing excitability with no cardiac risk
Resting membrane potential is unaffected by extracellular K+ changes
$E_K$ reaches exactly 0 mV, abolishing all electrical activity instantly

Correct Answer Logic:

Raising extracellular K+ reduces the outward K+ concentration gradient, shifting $E_K$ toward less negative values and depolarizing the resting membrane potential. Initially this increases excitability, but sustained depolarization inactivates voltage-gated Na+ channels, ultimately causing dangerous cardiac conduction defects and arrhythmias — the basis for ECG changes (peaked T waves, widened QRS) in hyperkalemia.

MBBS QUESTION #10174

Question 9190

The internal jugular vein, common carotid artery, and vagus nerve are bound together within which fascial sheath of the neck, a key relationship during neck surgery and central line placement?

Carotid sheath✔️
Pretracheal fascia
Prevertebral fascia
Investing layer of deep cervical fascia

Correct Answer Logic:

The carotid sheath, formed by contributions from all three layers of deep cervical fascia, encloses the common/internal carotid artery, internal jugular vein, and vagus nerve, keeping these vital structures anatomically related throughout the neck.

Mathematics QUESTION #978

Question 9192

Let $\alpha_\theta$ and $\beta_\theta$ be the distinct roots of $2x^2+(\cos\theta)x-1=0,\ \theta\in(0,2\pi)$. If $m$ and $M$ are the minimum and maximum values of $\alpha_\theta^4+\beta_\theta^4$, then $16(M+m)$ equals:

24
25✔️
17
27

Correct Answer Logic:

By Vieta's: $\alpha+\beta=-\frac{\cos\theta}{2}$, $\alpha\beta=-\frac{1}{2}$. Then $\alpha^2+\beta^2=(\alpha+\beta)^2-2\alpha\beta=\frac{\cos^2\theta}{4}+1$. And $\alpha^4+\beta^4=(\alpha^2+\beta^2)^2-2(\alpha\beta)^2=\left(\frac{\cos^2\theta}{4}+1\right)^2-\frac{1}{2}$. Let $u=\cos^2\theta\in[0,1]$. Max at $u=1$: $M=\frac{25}{16}-\frac{1}{2}=\frac{17}{16}$. Min at $u=0$: $m=1-\frac{1}{2}=\frac{1}{2}$. So $16(M+m)=16\cdot\frac{25}{16}=25$.

Maths QUESTION #7937

Question 9193

What is the L.C.M. of 25, 30, 35 and 40?

3800
4200✔️
4400
None

Correct Answer Logic:

To find the L.C.M., we use prime factorization:

$25 = 5^2$
$30 = 2 \times 3 \times 5$
$35 = 5 \times 7$
$40 = 2^3 \times 5$

L.C.M. $= 2^3 \times 3 \times 5^2 \times 7 = 8 \times 3 \times 25 \times 7 = 4200$

Question 9194

In urban climatology, what is the Urban Heat Island intensity typically measured as?

Temperature difference: urban vs rural✔️
Absolute urban temperature
Humidity levels
Wind speed reduction

Correct Answer Logic:

Urban Heat Island (UHI) intensity is measured as the temperature difference between urban and rural areas, typically 1-3°C (can reach 10°C+ at night). Caused by heat-absorbing surfaces, reduced vegetation, waste heat, and altered airflow—mitigated through green infrastructure and cool materials.

Question 9196

Which of the following is not a recognized principle of New Public Management (NPM)?

Privatization of public services
Competition among service providers
Empowerment of citizens as stakeholders✔️
None of these

Correct Answer Logic:

Empowerment of Citizens as a broad participatory principle is more associated with New Public Governance (NPG) and democratic governance models than with NPM. NPM's core principles include: privatization, competition, performance measurement, managerial autonomy, customer orientation, decentralization, and results-based management. While NPM treats citizens as 'customers,' it does not emphasize political empowerment or co-governance.

MBBS QUESTION #10240

Question 9197

An ECG shows progressive lengthening of the PR interval over several beats until a QRS complex is dropped entirely, after which the cycle repeats. This pattern describes:

Mobitz type I (Wenckebach) second-degree AV block✔️
Mobitz type II second-degree AV block
Third-degree (complete) AV block
First-degree AV block

Correct Answer Logic:

Wenckebach (Mobitz I) block is characterized by progressive PR prolongation culminating in a dropped beat, reflecting progressive AV nodal fatigue; it is usually benign and often reversible, in contrast to Mobitz II, which shows sudden dropped beats without preceding PR prolongation and carries a higher risk of progression to complete heart block.

CISA QUESTION #6853

Question 9198

An organization's business continuity plan designates a hot site for disaster recovery but has no documented procedures for activating the site or transitioning operations. What is the MOST critical gap?

Incomplete documentation
Having recovery infrastructure without activation procedures creates uncertainty during actual disasters✔️
Cost inefficiency
Lack of testing

Correct Answer Logic:

A hot site provides technical infrastructure but is useless without clear activation procedures and transition plans. During actual disasters, stress and confusion are high—detailed procedures are critical for successful activation. Without documented processes, the organization risks confusion, delays, and potential failure to successfully activate the expensive hot site.
