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.

Mathematics QUESTION #6943

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

Define problem
Collect data
Analyze data
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.

Which choice completes the text with the most logical and precise word or phrase?

attached
collected✔️
followed
replaced

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.

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. I have just seen a most beautiful thing, / Slim and still, / Against a gold, gold sky, / A straight black cypress, / Sensitive, / Exquisite, / A black finger / Pointing upwards. / Why, beautiful still finger, are you black? / And why are you pointing upwards?

Correct Answer Logic:

The speaker first describes seeing a cypress tree that looks like a finger, then wonders about its meaning by asking why it's black and pointing upward.

Paper-II (Pharmacognosy and Pharmaceutics-I) QUESTION #2952

Question 819

A prescription requires $250\text{ mg}$ of a drug, but the pharmacy only has a $5\%$ (w/v) solution. How many milliliters are needed?

2 ml
5 ml✔️
10 ml
50 ml

Correct Answer Logic:

$5\%$ w/v means $5\text{ g}$ in $100\text{ ml}$, or $50\text{ mg/ml}$. Calculation: $250\text{ mg} \div 50\text{ mg/ml} = 5\text{ ml}$.

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).
