Journalism / Mass Communication QUESTION #6355

Question 1862

The concept of entropy in communication theory refers to which of the following?

The total amount of information successfully transmitted across a noisy channel
The measure of uncertainty in a system, which increases in proportion to the number of possible messages from which a source must choose✔️
The physical degradation of a communication signal over long distances
The process by which redundancy is systematically removed to increase transmission speed

Correct Answer Logic:

Entropy is a concept borrowed from thermodynamics and information theory. In communication, it measures the degree of uncertainty or unpredictability in a message system. The greater the number of possible messages a source could send, the higher the entropy — because the receiver cannot predict with confidence what will arrive next. Consider a coin toss (low entropy, only two outcomes) versus selecting one square on a 64-square chessboard (high entropy, 64 possible outcomes). High entropy means more information value per message received, because the message resolves greater uncertainty. However, very high entropy also makes communication more difficult because there is little predictability to guide decoding. This is why communication systems balance entropy with redundancy — repeating or reinforcing elements that the receiver can use to reconstruct meaning even under noisy conditions.

Therapeutics and Patient Care QUESTION #3899

Question 1863

What is the most clinically important advantage of angiotensin II receptor blockers (ARBs) over ACE inhibitors in terms of tolerability?

There is a decreased incidence of hyperkalaemia
They are less likely to cause adverse effects such as dizziness
There is a reduced incidence of cough✔️
They do not interact with non-steroidal anti-inflammatory medications

Correct Answer Logic:

ACE inhibitors cause a dry persistent cough in up to $20\%$ of patients by increasing bradykinin levels. ARBs do not inhibit ACE and therefore have a significantly lower incidence of cough.

Education QUESTION #6747

Question 1865

A teacher uses weekly quizzes and classroom observations to adjust her teaching strategies mid-semester. A colleague argues this is not "real" assessment because no grades are assigned. Which argument best supports the teacher's approach?

Assessment requires grading; without it the process lacks accountability
The teacher is conducting formative assessment whose primary purpose is process improvement, not certification✔️
This qualifies only as measurement, not assessment, since no value judgment is made
Classroom observation is not a valid assessment tool and should be replaced with written tests

Correct Answer Logic:

Formative assessment is defined by its purpose — to improve the teaching-learning process through ongoing feedback — not by whether grades are assigned. Grades are a hallmark of summative assessment. Measurement generates data; assessment uses that data to enhance instruction. Observation is a recognized tool of formative assessment.

Question 1866

'Spatial databases' are also known as:

Geodatabases✔️
Mono-databases
Concurrent databases
None of these

Correct Answer Logic:

Spatial databases (also called geodatabases) are databases optimized to store, query, and manipulate data that represents objects defined in geometric space — particularly geographic features. The term 'geodatabase' is widely used in GIS (especially in ESRI's ArcGIS platform) to describe a database of spatial/geographic data with both location and attribute information.

Question 1867

The ______ is the chemical breakdown of a compound due to reaction with water.

Hydration
Oxidation
Hydrolysis✔️
None of these

Correct Answer Logic:

Hydrolysis is a chemical weathering process in which water reacts with minerals in rocks to form new compounds. For example, feldspar reacts with water to form clay minerals. Hydration is the absorption of water into the mineral structure, and oxidation involves reaction with oxygen. Hydrolysis is specifically the chemical breakdown via water reaction.

Journalism / Mass Communication QUESTION #6388

Question 1871

The Soviet Theory of the press, as described in the textbook, emerged after the Russian Revolution of 1917. Which of the following is NOT a feature of the Soviet Theory?

The media is closely tied to communist ideology
The media serves as a collective agitator, propagandist, and educator in building communism
No private ownership of the media is permitted
Journalists and media professionals have full editorial autonomy within their organisations✔️

Correct Answer Logic:

The Soviet Theory of the press emerged from Marxist-Leninist ideology after the 1917 Russian Revolution. Its key features are:

Closely tied to communist ideology — media is an instrument of the state/party
Media functions as a collective agitator, propagandist, and educator in building communism (Lenin's phrase)
No private ownership of media — all media belongs to the state or party
The government is superior to media institutions
Media is expected to be serious and purposeful

Full editorial autonomy for journalists is a feature of the Libertarian Theory, which is the direct opposite of the Soviet approach. Under Soviet theory, media professionals are instruments of the state's ideological goals — they have no independent editorial authority. The Soviet Theory does, however, propose a positive role for media: not merely reinforcing authority (as in Authoritarianism), but actively building a new communist society.

Verbal Reasoning QUESTION #8174

Question 1873

Given that $st = \sqrt{10}$, compare:

Quantity A: $s^2$

Quantity B: $\dfrac{10}{t^2}$

Quantity A is greater
Quantity B is greater
The two quantities are equal✔️
The relationship cannot be determined from the information given

Correct Answer Logic:

From $st = \sqrt{10}$, squaring both sides: $(st)^2 = 10$, so $s^2 t^2 = 10$.

Therefore $s^2 = \dfrac{10}{t^2}$.

Quantity A $= s^2 = \dfrac{10}{t^2} =$ Quantity B.

The two quantities are equal.

Electrical Engineering QUESTION #2193

Question 1876

In a CMOS inverter with $V_{DD} = 3.3\,\text{V}$, NMOS parameters $k_n = 2\,\text{mA/V}^2$, $V_{tn} = 0.5\,\text{V}$, and PMOS parameters $k_p = 1\,\text{mA/V}^2$, $|V_{tp}| = 0.5\,\text{V}$, the switching threshold $V_M$ (where $V_{out} = V_{in}$) is approximately:

$1.26\,\text{V}$✔️
$1.65\,\text{V}$
$0.99\,\text{V}$
$2.00\,\text{V}$

Correct Answer Logic:

$V_M = \frac{V_{tn}+\sqrt{k_p/k_n}(V_{DD}-|V_{tp}|)}{1+\sqrt{k_p/k_n}} = \frac{0.5+\sqrt{0.5}(2.8)}{1+\sqrt{0.5}} = \frac{0.5+1.980}{1.707} = \frac{2.480}{1.707} \approx 1.26\,\text{V}$. The threshold is below $V_{DD}/2 = 1.65\,\text{V}$ because $k_p < k_n$.

Reading and Writing (Module-1) QUESTION #5358

Question 1880

Transgenic fish have genetic material from other species. Some contain jellyfish DNA, causing them to glow. Originally created for labs in the 90s, they became pets later and are now appearing in Brazilian rivers. A student suggests their escape from farms could lead to long-term ecological damage. Which quotation from a researcher would best support the student's assertion?

'In one site in the wild where transgenic fish were observed, females outnumbered males, while in another the numbers of females and males were equivalent.'
'Though some presence of transgenic fish in the wild has been recorded, there are insufficient studies of the impact of those fish on the ecosystems into which they are introduced.'
'The ecosystems into which transgenic fish are known to have been introduced may represent a subset of the ecosystems into which the fish have actually been introduced.'
'Through interbreeding, transgenic fish might introduce the trait of fluorescence into wild fish populations, making those populations more vulnerable to predators.'✔️

Correct Answer Logic:

Option D provides a specific negative ecological outcome (vulnerability to predators) resulting from the transgenic trait entering the wild population.
