Question 5
The recommended concentration of fluoride ion in drinking water is up to 1 ppm. At this level, fluoride hardens tooth enamel by converting $[3Ca_3(PO_4)_2 \cdot Ca(OH)_2]$ (hydroxyapatite) to:
Correct Answer Logic:
Fluoride ions replace the hydroxide ions in hydroxyapatite: $3Ca_3(PO_4)_2 \cdot Ca(OH)_2 + 2F^- \to 3Ca_3(PO_4)_2 \cdot CaF_2 + 2OH^-$. The product, fluoroapatite $[3Ca_3(PO_4)_2 \cdot CaF_2]$, is harder and more resistant to acid attack than hydroxyapatite, thus protecting teeth from decay.

Correct Answer Logic:
The liver possesses the enzymes to synthesize ketone bodies but lacks thiophorase, required to reactivate acetoacetate back to acetoacetyl-CoA for further metabolism; this ensures ketone bodies are exported for use as fuel by extrahepatic tissues (brain, heart, skeletal muscle) rather than being consumed by the liver that produces them.

Correct Answer Logic:
Degree holders: \(0.20 \times 800 = 160\); of these, managers \(= 80\). Non-degree: \(640\); managers among them \(= 0.30 \times 640 = 192\). Total managers \(= 80 + 192 = 272\).

Correct Answer Logic:
Predictive churn modelling integrates MIS (data infrastructure, machine learning algorithms applied to loyalty data) with CRM/marketing strategy (targeted retention interventions). The critical ethical dimension is data privacy: the General Data Protection Regulation (GDPR) and Pakistan's Personal Data Protection Bill require that customers provide informed consent for their data to be used for profiling and automated decision-making. Using loyalty data for predictive targeting without explicit consent is a regulatory violation regardless of its commercial effectiveness.

Correct Answer Logic:
An integrating element: \(\dot{x}_o(t)=K_I x_i(t)\), so \(sX_o(s)=K_I X_i(s)\), giving \(Y(s)=K_I/s\). Integration in time corresponds to division by \(s\) in the Laplace domain.

QUESTION #1696
Question 17
An expansionary monetary policy that increases the money supply is most likely to have a direct positive effect on which of the following macroeconomic variables?
Correct Answer Logic:
In the short run, an increase in the money supply (\(\uparrow M_s\)) can stimulate aggregate demand and temporarily reduce unemployment. However, according to the Quantity Theory of Money (\(MV = PQ\)), in the long run an increase in money supply primarily leads to higher inflation (price level increases). The classical dichotomy holds that money is neutral in the long run, so real economic growth is determined by supply-side factors, not money supply.

Which of the following is a field?
Correct Answer Logic:
$\mathbb{Q}(\sqrt{2}) = \{a+b\sqrt{2}: a,b\in\mathbb{Q}\}$ is a field β it is closed under addition, subtraction, multiplication, and division (every non-zero element has a multiplicative inverse: $(a+b\sqrt{2})^{-1} = \frac{a-b\sqrt{2}}{a^2-2b^2}\in\mathbb{Q}(\sqrt{2})$ when $a^2\neq 2b^2$). It is an extension field of $\mathbb{Q}$.
