Agronomy QUESTION #2062
Question 2422
In drip fertigation, urea is preferred over ammonium nitrate for nitrogen supply primarily because:
  • Urea has higher N content (46%) and remains soluble in irrigation water without precipitating or corroding drip emitters under normal conditions✔️
  • Ammonium nitrate is less soluble in water
  • Urea immediately converts to nitrate before entering drip lines
  • Ammonium nitrate causes salt injury to crops when fertigated
Correct Answer Logic:
Urea (46% N) is the most commonly fertigated N source because it is highly soluble (1080 g/L at 20°C), non-ionic (does not react with Ca, Mg, or carbonates in irrigation water to precipitate), and non-corrosive to metal emitters. Ammonium nitrate, while soluble, can react with hard water and poses explosion risk in storage.

Mathematics QUESTION #4101
Question 2435
The Maclaurin series for \(f(Z)=Z^2e^{3Z}\), using \(e^{3Z}=\displaystyle\sum_{n=0}^{\infty}\dfrac{3^nZ^n}{n!}\), begins as:
  • \(Z^2+3Z^3+\dfrac{9}{2}Z^4+\cdots\)✔️
  • \(Z^2+3Z^3+\dfrac{9}{2}Z^4+\dfrac{9}{2}Z^5+\cdots\)
  • \(1+3Z+\dfrac{9Z^2}{2}+\cdots\)
  • \(Z^2+Z^3+Z^4+\cdots\)
Correct Answer Logic:
\(Z^2e^{3Z}=Z^2\sum_{n=0}^\infty\dfrac{3^nZ^n}{n!}=Z^2+3Z^3+\dfrac{3^2}{2!}Z^4+\dfrac{3^3}{3!}Z^5+\cdots = Z^2+3Z^3+\dfrac{9}{2}Z^4+\dfrac{9}{2}Z^5+\cdots\).

Economics QUESTION #1701
Question 2439
Among the most persistent structural criticisms levelled at Pakistan's privatisation drives since the 1990s, which of the following has been the most prominent?
  • Significant decline in government tax revenues post-privatisation
  • Absence of transparency, competitive bidding, and accountability in the divestiture process✔️
  • Excessive regulatory burden imposed on newly privatised entities
  • None of these
Correct Answer Logic:
The most consistent and widely documented criticism of Pakistan's privatisation policy is the lack of transparency and accountability — assets were often sold below fair market value, through non-competitive processes, to politically connected buyers. The privatisation of entities like PTCL, Pakistan Steel Mills deliberations, and banking sector sales have all attracted scrutiny on these grounds. Regulatory capture of privatised sectors, not over-regulation, has also been a concern.
