Which is a synthetic polymer?
  • Polystyrene
  • Polyethylene
  • PVC✔️
  • None
Correct Answer Logic:
All three — polystyrene, polyethylene, and PVC — are synthetic polymers. However, if only one must be chosen, PVC (polyvinyl chloride) is the most distinctly synthetic and industrially significant; the paper marks 'None' suggesting all three are correct but none alone fully answers.

Question 804

If $\begin{pmatrix}1&1\\0&1\end{pmatrix}\begin{pmatrix}1&2\\0&1\end{pmatrix}\begin{pmatrix}1&3\\0&1\end{pmatrix}\cdots\begin{pmatrix}1&n-1\\0&1\end{pmatrix} = \begin{pmatrix}1&78\\0&1\end{pmatrix}$, find the inverse of $\begin{pmatrix}1&n\\0&1\end{pmatrix}$.

  • $\begin{pmatrix}1&0\\12&1\end{pmatrix}$
  • $\begin{pmatrix}1&-13\\0&1\end{pmatrix}$
  • $\begin{pmatrix}1&-12\\0&1\end{pmatrix}$✔️
  • $\begin{pmatrix}1&0\\13&1\end{pmatrix}$
Correct Answer Logic:

The product of upper-triangular matrices $\begin{pmatrix}1&k\\0&1\end{pmatrix}$ gives $\begin{pmatrix}1&\sum k\\0&1\end{pmatrix}$.

$\sum_{k=1}^{n-1}k = \dfrac{(n-1)n}{2} = 78 \Rightarrow n(n-1)=156 \Rightarrow n=13$

The inverse of $\begin{pmatrix}1&n\\0&1\end{pmatrix} = \begin{pmatrix}1&13\\0&1\end{pmatrix}$ is $\begin{pmatrix}1&-13\\0&1\end{pmatrix}$.

Biology Zoology Botany QUESTION #1384
Question 809
Which group of organisms is known for having chloroplasts in every cell?
  • Fungi
  • Algae✔️
  • Bryophytes
  • Lichens
Correct Answer Logic:
Algae contain chloroplasts in every photosynthetic cell of their thallus. Algal chloroplasts come in diverse shapes (cup-shaped, ribbon-like, stellate) and contain photosynthetic pigments. Fungi have no chloroplasts at all (they are heterotrophs). Bryophytes have chloroplasts in their green cells but not every cell (e.g., rhizoids lack them). Lichens are fungal-algal symbioses.

CISA QUESTION #6840
Question 810
  1. Define problem
  2. Collect data
  3. Analyze data
  4. Draw conclusions
An organization's audit methodology skips directly from problem definition to conclusions without data collection or analysis. What is the PRIMARY consequence?
  • Faster audit completion
  • Conclusions lack evidentiary support and are essentially opinions rather than audit findings✔️
  • Reduced audit costs
  • Increased efficiency
Correct Answer Logic:
The scientific method and audit methodology require evidence-based conclusions. Skipping data collection and analysis means conclusions are based on assumptions or opinions rather than facts. This violates the fundamental audit principle that findings must be supported by sufficient, relevant, and reliable evidence.

Agronomy QUESTION #2032
Question 812
Multiple cropping differs from mono-cropping in that multiple cropping:
  • Uses more synthetic inputs per unit area
  • Grows two or more crops on the same land in the same year, either sequentially or simultaneously, achieving greater land productivity (LER > 1)✔️
  • Exclusively refers to relay cropping where crops are planted before the previous crop is harvested
  • Requires larger farm machinery and is only feasible on large farms
Correct Answer Logic:
Multiple cropping grows more than one crop per year on the same land (double, triple cropping or intercropping). Land Equivalent Ratio (LER) measures efficiency: LER > 1 means intercropping is more productive per unit land than monoculture. It improves resource use efficiency and farm income.

Boilers Mechanical Engineering QUESTION #3988
Question 816
'Scaling' on the internal surfaces of a boiler tube is dangerous because it:
  • Makes the boiler look old
  • Acts as an insulator, causing the metal to overheat and fail✔️
  • Increases the weight of the boiler
  • Makes the water taste bad
Correct Answer Logic:
Scale has low thermal conductivity; heat cannot transfer to water, causing the tube metal to reach melting/weakening points.

Disaster Management QUESTION #6557
Question 817
Which approach to disaster recovery monitoring would most effectively ensure accountability and learning?
  • Financial audits only
  • Combining real-time digital tracking, community feedback mechanisms, independent evaluations, and documentation of lessons learned✔️
  • Government reports
  • Donor assessments
Correct Answer Logic:
Section 10.1 emphasizes monitoring recovery with clear indicators, transparency mechanisms, and incorporating community feedback. Effective monitoring combines quantitative tracking, qualitative community input, independent verification, and learning systems rather than relying on single sources.

Question 818
The following text is from the 1923 poem "Black Finger" by Angelina Weld Grimké, a Black American writer. A cypress is a type of evergreen tree.

Which choice best describes the overall structure of the text?

Chemistry QUESTION #1103
Question 820
Predict major product 'P': cyclopentyl methyl ketone \(\xrightarrow{\text{(i) HBr, benzoyl peroxide}}\xrightarrow{\text{(ii) KCN}}\xrightarrow{\text{(iii) Na(Hg)/C}_2\text{H}_5\text{OH}}\) P:
  • Cyclopentyl group with CH\(_3\) and NC substituents
  • NC–CH(CH\(_3\))–cyclopentyl
  • Cyclopentane ring with CH\(_3\) and CH\(_2\)NH\(_2\)
  • Cyclopentane ring with CH\(_3\) and CH\(_2\)NH\(_2\) (exocyclic)✔️
Correct Answer Logic:
(i) HBr with peroxide = anti-Markovnikov addition → CH\(_2\)Br at the end of the methyl chain (allylic/radical). (ii) KCN substitutes Br → –CH\(_2\)CN. (iii) Na(Hg)/EtOH reduces CN → –CH\(_2\)NH\(_2\). Major product: cyclopentyl group bearing –CH\(_3\) transformed to –CH\(_2\)NH\(_2\) substituent = option (4).
