The Title 28 of the United States Code QUESTION #3722

Question 487

A shopper in a grocery store slips on a banana peel that is dark brown and flattened. There are no witnesses to when it fell. To win a negligence case, what must the shopper prove regarding the store's 'notice'?

The store had 'actual notice' (an employee saw it fall).
The store had 'constructive notice' (it was there long enough that the store should have discovered it).✔️
Nothing; stores are strictly liable for slip-and-falls.
The store failed to have a 'banana-free' policy.

Correct Answer Logic:

In premises liability, if the defendant did not have actual notice of the hazard, the plaintiff must show constructive notice. The dark, flattened state of the peel suggests it had been there for a significant amount of time.

Question 489

The keys were found __________ the drawer where you left them last week.

under
in✔️
on
beside

Correct Answer Logic:

The preposition 'in' is correct here because keys are located inside a drawer. 'Under' means beneath, 'on' means on top of a surface, and 'beside' means next to — none of these fit the context of being inside a drawer.

Electrical Engineering QUESTION #2156

Question 494

A three-phase 50 Hz star-connected synchronous generator has $X_s = 5\,\Omega$/phase (resistance negligible). It delivers rated current at 0.8 pf lagging with terminal voltage $V_t = 11\,\text{kV}$ (line). The excitation EMF $E_f$ per phase is approximately:

$7{,}351\,\text{V}$✔️
$6{,}350\,\text{V}$
$8{,}660\,\text{V}$
$9{,}100\,\text{V}$

Correct Answer Logic:

$V_{ph} = \frac{11000}{\sqrt{3}} \approx 6350\,\text{V}$. Using $E_f = \sqrt{(V\cos\phi)^2 + (V\sin\phi + IX_s)^2}$ with rated current and 0.8 lag pf gives $E_f \approx 7351\,\text{V}$.

Economics QUESTION #1712

Question 497

Pakistan's water crisis is widely recognised as a compound problem with multiple reinforcing drivers. Which comprehensive assessment best captures the causality behind the country's deepening water stress?

Inefficient irrigation systems and poor canal maintenance leading to massive water losses
Rapid population growth and urbanisation expanding water demand beyond sustainable supply
Glacial retreat, erratic precipitation patterns, and rising temperatures from climate change
All of these✔️

Correct Answer Logic:

Pakistan's water scarcity is a multi-causal crisis: (1) Governance and infrastructure failures — the Indus Basin irrigation system loses an estimated 40% of water to seepage and evaporation; (2) Demand pressure — Pakistan's population growth (one of the highest in Asia) and urban expansion continuously expand water demand; (3) Climate change — accelerating glacial melt (short-term flood risk), long-term reduction in glacier-fed river flows, and shifting monsoon patterns all exacerbate supply-side constraints.
