Journalism / Mass Communication QUESTION #6417

Question 7

The first wide-coverage telex network was implemented in which country and for what primary purpose?

United States, for commercial business communication in 1945
Germany, in the 1930s, used primarily for government communication — allowing up to 25 telex channels to share a single long-distance telephone line at 45.5 bits per second✔️
Britain, in the 1920s, for military communication during World War I
Japan, in the 1950s, for international business communication

Correct Answer Logic:

The telex system represented an important intermediate stage between the telegraph and modern digital data communication. According to the textbook:

Telex machines first appeared as an evolution of telegraph technology, using telephone-like rotary dialing to connect teleprinters (teletypes)
By 1935, message routing was the last barrier to full automation of the system
The first wide-coverage telex network was implemented in Germany in the 1930s, used primarily for government communication
Technical specifications: 45.5 bits per second; up to 25 telex channels could share a single long-distance telephone channel
This made telex the least expensive method of reliable long-distance communication at the time

Telex eventually became a global business standard for transmitting documents internationally, particularly important for news agencies (like Reuters) and international trade, before being superseded by fax and then email in the late 20th century.

Geography QUESTION #6349

Question 11

The 'demographic dividend' in development economics refers to:

Population growth accelerating economic expansion
Economic growth potential from declining dependency ratios when working-age population exceeds dependents✔️
Government payments to families with children
Youthful population ensuring future labor supply

Correct Answer Logic:

Demographic dividend occurs when fertility declines, creating a temporary period where working-age population (15-64) grows faster than dependents (children + elderly). This offers economic growth opportunity if the working-age population is productively employed, as seen in East Asian tiger economies.

CISA QUESTION #6864

Question 12

An auditor reviews key performance indicators for IT service desk and finds that the primary metric is 'number of tickets closed per day' with staff bonuses tied to this metric. What is the PRIMARY risk of this metric design?

Insufficient metrics
Incentivizes quantity over quality—staff may close tickets without proper resolution✔️
Excessive focus on efficiency
Lack of customer satisfaction measures

Correct Answer Logic:

Metrics that reward quantity without quality drive dysfunctional behavior. Tying bonuses to tickets closed incentivizes staff to close tickets quickly without proper resolution, leading to recurring problems, poor service quality, and customer dissatisfaction. Effective metrics must balance quantity, quality, and customer satisfaction.

Constitutional Law QUESTION #5819

Question 17

A public university fired a tenured professor without a hearing after he was accused of plagiarism. The university claimed that because he was an 'at-will' employee, no hearing was required. Does the professor have a valid claim?

No, because public employment is a privilege, not a right.
No, because plagiarism is a clear violation of university policy.
Yes, because tenure creates a 'property interest' in employment that requires procedural due process.✔️
Yes, because the firing violated his First Amendment right to academic freedom.

Correct Answer Logic:

Tenured public employees have a 'legitimate claim of entitlement' to their jobs, which constitutes a property interest under the Due Process Clause of the 14th Amendment. They cannot be fired without notice and a pre-termination hearing.

Natural levees are associated with:

Alluvial fans
Flood plains✔️
Deltas
None of these

Correct Answer Logic:

Natural levees are low ridges of alluvial sediment built up along the banks of a river, formed when floodwaters overflow and deposit their heaviest sediment load immediately adjacent to the channel. They are characteristic features of flood plains. As the river repeatedly floods, these ridges grow higher and help confine the river channel.

Pharmacokinetics and Pharmacodynamics QUESTION #3849

Question 19

Given $\text{Na}\ M_r = 23$ and $\text{Cl}\ M_r = 35$, what is the sodium ion concentration of a $0.9\%\ \text{w/v}$ sodium chloride solution?

$100\ \text{mmol/L}$
$130\ \text{mmol/L}$
$150\ \text{mmol/L}$✔️
$270\ \text{mmol/L}$

Correct Answer Logic:

$0.9\%\ \text{NaCl} = 9\ \text{g/L}$. $M_r$ of NaCl $= 23 + 35 = 58\ \text{g/mol}$. Moles $= \dfrac{9}{58} = 0.1552\ \text{mol/L} \approx 155\ \text{mmol/L} \approx 150\ \text{mmol/L}$.

Chemistry QUESTION #5581

Question 20

In the reaction sequence $CH_3COOH \xrightarrow{LiAlH_4} A \xrightarrow{PCl_5} B \xrightarrow{Alc.\ KOH} C$, the product C is:

Ethylene ($CH_2=CH_2$)✔️
Acetyl chloride ($CH_3COCl$)
Acetaldehyde ($CH_3CHO$)
Acetylene ($HC\equiv CH$)

Correct Answer Logic:

Step 1: $CH_3COOH \xrightarrow{LiAlH_4} CH_3CH_2OH$ (ethanol, A). Step 2: $CH_3CH_2OH \xrightarrow{PCl_5} CH_3CH_2Cl$ (chloroethane, B). Step 3: $CH_3CH_2Cl \xrightarrow{Alc.\ KOH} CH_2=CH_2$ (ethylene/ethene, C) by elimination. The final product C is ethylene.
