Correct Answer Logic:
From Arrhenius equation: $k = Ae^{-E_a/RT}$. As $E_a$ increases (at constant T), $k$ decreases — Plot I (k vs $E_a$ as a decreasing curve) is correct. As T increases (at constant $E_a$), $k$ increases exponentially — Plot II (k vs T as an increasing curve) is correct. Both plots are correct representations.

Correct Answer Logic:

Use the identity: $\dfrac{{}^{20}C_{i-1}}{{}^{20}C_i + {}^{20}C_{i-1}} = \dfrac{{}^{20}C_{i-1}}{{}^{21}C_i} = \dfrac{i}{21}$

So the sum becomes: $\displaystyle\sum_{i=1}^{20}\left(\frac{i}{21}\right)^3 = \frac{1}{21^3}\sum_{i=1}^{20}i^3 = \frac{1}{21^3}\cdot\left(\frac{20\cdot21}{2}\right)^2 = \frac{(210)^2}{21^3} = \frac{44100}{9261} = \frac{200}{21}$

Therefore $k = \mathbf{200}$.

Correct Answer Logic:

1. Variable Cost per unit = ($90,000 + $6,000) / 6,000 = $16.
2. Contribution per unit = $40 - $16 = $24.
3. Total Fixed Costs = $54,000 + $21,000 = $75,000.
4. Required Units = (Fixed Costs + Target Profit) / Contribution = ($75,000 + $45,000) / $24 = 5,000 units.

Question 1707
In the context of Green Building design, the Overall Thermal Transfer Value (OTTV) is a metric used to evaluate:
  • The amount of heat generated by building occupants and equipment per unit floor area
  • The total heat gain through the building envelope (walls, roofs, and fenestration) per unit area of the building facade, used to set energy performance benchmarks✔️
  • The coefficient of performance (COP) of the HVAC system
  • The total solar radiation incident on the building roof per year
Correct Answer Logic:
OTTV (Overall Thermal Transfer Value, in W/m²) is an energy code metric used in tropical and subtropical regions (including ECBC in Pakistan/India) that quantifies the total heat gain through the building envelope per unit external wall area. It accounts for conduction through opaque walls, solar radiation through windows (WWR, SHGC), and conductive heat through glazing. A lower OTTV indicates a more thermally efficient building envelope.

Question 1709
Methanol ($CH_3OH$) is produced by reduction of:
  • Formaldehyde ($HCHO$)✔️
  • Acetaldehyde ($CH_3CHO$)
  • Propanal ($C_2H_5CHO$)
  • Propanone ($CH_3COCH_3$)

Question 1714
In gymnosperms, the pollen chamber represents:
  • The microsporangium in which pollen grains develop
  • A cell in the pollen grain in which the sperms are formed
  • A cavity in the ovule in which pollen grains are stored after pollination✔️
  • An opening in the megagametophyte through which the pollen tube approaches the egg
Correct Answer Logic:
The pollen chamber in gymnosperms is a cavity formed in the nucellus of the ovule where pollen grains are deposited after pollination. It is a temporary chamber that forms by degeneration of nucellar cells near the micropyle. From here, pollen grains germinate and the tube grows toward the archegonia.

Civil Procedure QUESTION #3697
Question 1718
A plaintiff sues a defendant in federal court. After the plaintiff rests at trial, the defendant moves for JMOL under Rule 50(a). The judge denies the motion. The defendant then presents evidence and rests. The jury returns a verdict for the plaintiff. The defendant does NOT file a renewed JMOL within 28 days. Can the defendant challenge the sufficiency of the evidence on appeal?
  • Yes, because the Rule 50(a) motion preserved the issue.
  • No, a post-verdict motion under Rule 50(b) is required to preserve a challenge to the sufficiency of the evidence on appeal.✔️
  • Yes, under the plain error doctrine.
  • No, unless the judge specifically invited an appeal.
Correct Answer Logic:
According to the Supreme Court in Unitherm Food Systems, Inc. v. Swift-Eckrich, Inc., a party's failure to file a Rule 50(b) motion post-verdict precludes an appellate court from reviewing the sufficiency of the evidence.
