Tourism & Hospitality Management QUESTION #1582

In the context of Pakistan's tourist destinations, which of the following categories correctly classifies the tourism resources covered in the course?

Only natural and cultural heritage resources
Natural resources (landforms, water bodies, biota), cultural heritage resources (Muslim, Buddhist, Sikh, Hindu), and neotourism (ecotourism, medical, MICE, pilgrimage)✔️
Adventure sports and gastronomic tourism only
National parks, hill stations, and urban commercial attractions only

Correct Answer Logic:

The Pakistan Tourist Destinations course systematically classifies resources into three categories: natural (mountains, deserts, beaches, flora-fauna), cultural heritage (multi-religious sites, fairs, museums), and neotourism destinations (ecotourism, camping, medical, MICE, pilgrimage tourism, and CPEC benefits).

Question 2

A transformer rated 10 MVA, 33/11 kV has a per-unit impedance of $0.05\,\text{pu}$ on its own base. On a new system base of 100 MVA and 33 kV (HV side), the per-unit impedance becomes:

$0.5\,\text{pu}$✔️
$0.005\,\text{pu}$
$0.05\,\text{pu}$
$5\,\text{pu}$

Correct Answer Logic:

$Z_{pu,new} = Z_{pu,old} \times \frac{MVA_{base,new}}{MVA_{base,old}} \times \left(\frac{kV_{base,old}}{kV_{base,new}}\right)^2 = 0.05 \times \frac{100}{10} \times 1 = 0.5\,\text{pu}$.

Question 5

Which one is the correct dimensional formula for capacitance in Farad? ($M, L, T, C$ stand for mass, length, time and charge):

$[F] = [C^2 M^{-1} L^{-2} T^2]$✔️
$[F] = [C^2 M^{-2} L^2 T^2]$
$[F] = [CM^{-2}L^{-2}T^{-2}]$
$[F] = [CM^{-1}L^{-2}T^2]$

Correct Answer Logic:

Capacitance $C = \frac{Q}{V} = \frac{Q}{\frac{W}{Q}} = \frac{Q^2}{W}$. Dimensions: $\frac{C^2}{M L^2 T^{-2}} = C^2 M^{-1} L^{-2} T^2$.

Question 6

A train moves at $72$ km/h. Its speed in m/s is:

15 m/s
20 m/s✔️
25 m/s
30 m/s

Correct Answer Logic:

Conversion: $72 \times (5/18) = 4 \times 5 = 20$ m/s.

Question 7

In a trial for bank fraud, the prosecution offers a summary chart of 5,000 separate wire transfers. The defense objects that the actual wire transfer records were not introduced. How should the court rule?

Sustain, because the actual records are the 'Best Evidence' under Rule 1002.
Overrule, under Rule 1006 (Summaries to Prove Content), provided the underlying records are voluminous and were made available to the defense for inspection.✔️
Sustain, unless the chart was prepared by a certified public accountant.
Overrule, because charts are always admissible as 'demonstrative evidence.'

Correct Answer Logic:

Rule 1006 allows a party to use a summary, chart, or calculation to prove the content of voluminous writings that cannot be conveniently examined in court, provided the originals are available for inspection.

Question 8

Find the amount if $\$800$ is invested at $6\%$ simple interest for $2$ years.

$\$896$✔️
$\$900$
$\$848$
$\$912$

Correct Answer Logic:

Interest $= (800 \times 6 \times 2)/100 = 96$. Amount $= 800 + 96 = 896$.

Question 9

The hoop (circumferential) stress $\sigma_h$ in a thin-walled cylinder (wall thickness $t$, internal diameter $d$, internal pressure $p$) is:

$\sigma_h = pd/(4t)$
$\sigma_h = pd/(2t)$✔️
$\sigma_h = 2pd/t$
$\sigma_h = pt/d$

Correct Answer Logic:

For a thin-walled cylinder ($t<0.1d$), hoop stress: $\sigma_h=pd/(2t)=pr/t$. The longitudinal stress is half: $\sigma_l=pd/(4t)=\sigma_h/2$.

Question 12

In a certain camera, four identical thin convex lenses are arranged axially in contact. Power and magnification compared to individual lens (power $p$, magnification $m$):

4p and $m^4$✔️
p^4 and $m^4$
4p and 4m
p^4 and 4m

Correct Answer Logic:

Power of lenses in contact adds: $P_{total}=4p$. For magnification: lenses in contact act as one system, but if we consider each lens magnifying, total magnification $= m\times m\times m\times m = m^4$. Answer: 4p and $m^4$.
