Question 1902
The $9:3:3:1$ ratio of the law of independent assortment can be affected by:
  • Genetic drift
  • Small population
  • Gene linkage✔️
  • Gene duplication
Correct Answer Logic:
Gene linkage occurs when two genes are on the same chromosome, so they do not assort independently, disrupting the expected $9:3:3:1$ dihybrid ratio.

Law QUESTION #9491
Question 1905
A's suit against B was dismissed for default when A failed to appear on the date of hearing. A applies for restoration, which is also dismissed. A then files a fresh suit on the same cause of action claiming the earlier dismissal was not on merits. B raises the plea of res judicata. Is the second suit barred?
  • Yes; dismissal for default operates as res judicata
  • No; but A must pay the costs of the previous suit
  • Yes; two dismissals operate as constructive res judicata
  • No; an order of dismissal for default is expressly excluded from the definition of 'decree' under the CPC and does not operate as res judicata✔️
Correct Answer Logic:
Section 2(2) CPC expressly provides that a decree shall not include 'any order of dismissal for default.' Dismissal for default is not a decision on merits. Therefore, it does not operate as res judicata, and a fresh suit on the same cause of action is maintainable, subject to limitation.

Verbal Reasoning QUESTION #8154
Question 1907

Runner A completed a distance of $\dfrac{4}{5}$ kilometer, while Runner B ran 800 meters. Compare the distances covered by each runner.

Quantity A: The distance Runner A ran

Quantity B: The distance Runner B ran

  • 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:

Convert both distances to the same unit.

Runner A ran $\dfrac{4}{5}$ km $= 0.8$ km $= 800$ meters.

Runner B ran $800$ meters.

Both runners covered exactly the same distance: 800 meters.

Therefore the two quantities are equal.

Planning QUESTION #4963
Question 1908
What does 'Gentrification' typically result in?
  • Neighborhood decline
  • Displacement of lower-income residents✔️
  • Improved affordable housing

Civil Engineering QUESTION #6653
Question 1909
What happens if a RC beam is 'Over-reinforced'?
  • The steel yields before the concrete crushes
  • The concrete crushes before the steel yields✔️
  • The beam will never fail
  • The deflection will be very large before failure
Correct Answer Logic:
An over-reinforced beam fails suddenly (brittle failure) because the concrete reaches its compressive limit while the steel is still in the elastic range.

HR and Management QUESTION #6479
Question 1910

The concept of 'retention of workforce' specifically focuses on:

  • Preventing any employee departures
  • Preventing undesirable detachments of talented and motivated workers✔️
  • Reducing total headcount systematically

Nursing QUESTION #9214
Question 1911
A researcher calculates Cronbach's Alpha (\(\alpha = 0.87\)) for a 20-item nursing satisfaction questionnaire. What does this indicate?
  • The tool has poor internal consistency and needs revision
  • The tool has excellent validity and measures what it intends to
  • The tool has good internal consistency reliability✔️
  • The tool is valid only for populations with similar cultural backgrounds
Correct Answer Logic:
Correct Answer: C — Good internal consistency reliability

Cronbach's Alpha (\(\alpha\)) measures the internal consistency of a multi-item scale — the degree to which items within the scale measure the same construct.

Interpretation benchmarks:
Cronbach's \(\alpha\)Internal Consistency
\(\alpha \geq 0.90\)Excellent
\(0.80 \leq \alpha < 0.90\)Good
\(0.70 \leq \alpha < 0.80\)Acceptable
\(0.60 \leq \alpha < 0.70\)Questionable
\(\alpha < 0.60\)Poor — tool needs revision
\(\alpha = 0.87\) falls in the 'Good' range, meaning the 20 items are cohesively measuring the same concept. Cronbach's Alpha measures reliability, not validity — a distinction critical for Head Nurse research appraisal.

Nursing QUESTION #9241
Question 1912
A Head Nurse notes a patient's pulmonary artery wedge pressure (PAWP) is \(22 \text{ mmHg}\). What does this MOST likely indicate in the context of a hypotensive ICU patient?
  • Hypovolemia — fluid resuscitation is needed
  • Pulmonary arterial hypertension
  • Left ventricular failure with pulmonary congestion✔️
  • Right ventricular failure — start inhaled nitric oxide
Correct Answer Logic:
Correct Answer: C — Left ventricular failure with pulmonary congestion

PAWP (Pulmonary Artery Wedge Pressure) Interpretation:
PAWPInterpretation
\(< 8 \text{ mmHg}\)Hypovolemia — aggressive fluid resuscitation
\(8 - 12 \text{ mmHg}\)Normal
\(12 - 18 \text{ mmHg}\)Mild-moderate elevation — monitor
\(> 18 \text{ mmHg}\)LV failure / pulmonary congestion
\(> 25 \text{ mmHg}\)Severe LV failure / cardiogenic pulmonary edema
PAWP (also called PCWP) reflects left atrial pressure and left ventricular end-diastolic pressure (preload). PAWP \(= 22 \text{ mmHg}\) indicates fluid overload or LV failure. Hypotension with elevated PAWP = cardiogenic shock. Management: diuretics, inotropes (dobutamine), vasopressors.

Contracts QUESTION #5851
Question 1914
A Farmer agrees to sell his entire upcoming corn crop to a Food Processor. A freak frost destroys the crop before harvest. Is the Farmer's performance excused?
  • No, because the Farmer assumed the risk of weather.
  • Yes, under the doctrine of 'Commercial Impracticability'.✔️
  • No, because the Farmer could buy corn elsewhere to fulfill the contract.
  • Yes, but only if the contract was for more than $5,000.
Correct Answer Logic:
Under UCC §2-615, delay in delivery or non-delivery is not a breach if performance has been made impracticable by the occurrence of a contingency, like a natural disaster.

Chemistry QUESTION #5518
Question 1917

Match the drugs in Column I with the appropriate chemical test in Column II:

Column I Column II
(A) Chloroxylenol (P) Carbylamine test
(B) Norethindrone (Q) Sodium hydrogencarbonate test
(C) Sulphapyridine (R) Ferric chloride test
(D) Penicillin (S) Bayer's test
  • $A \to R;\ B \to P;\ C \to S;\ D \to Q$✔️
  • $A \to Q;\ B \to S;\ C \to P;\ D \to R$
  • $A \to R;\ B \to S;\ C \to P;\ D \to Q$
  • $A \to Q;\ B \to P;\ C \to S;\ D \to R$
Correct Answer Logic:

Chloroxylenol contains a phenolic –OH group → Ferric chloride test (R). Norethindrone has a primary amine group → Carbylamine test (P). Sulphapyridine contains a C=C double bond (unsaturation) → Bayer's test (S). Penicillin is a carboxylic acid → Sodium hydrogencarbonate test (Q). So: $A \to R,\ B \to P,\ C \to S,\ D \to Q$.
