The sentence sets up a contrast: the filmmaker is known for aesthetic (artistic/visual) qualities, not for some other quality described in the blank. Since she does not speak out on political matters, the missing quality must be related to politics or controversy.

• Polemical — means controversial, argumentative, or politically charged. This directly fits the contrast: aesthetic vs. polemical qualities.
• Cinematic — essentially synonymous with aesthetic in the context of film; not a contrast.
• Narrative — refers to storytelling style; not linked to the political theme.
• Commercial — relates to box-office value; does not address the political angle.

Correct Answer: A — Polemical. The sentence contrasts aesthetic with polemical (politically contentious) qualities.

The Oral Polio Vaccine (OPV) is the most heat-sensitive of all vaccines used in the Expanded Programme on Immunization (EPI). It must be stored at -15°C to -25°C at the national and provincial level. However, at the district/peripheral level, OPV can be stored at +2°C to +8°C for short periods. The option -15°C to -25°C is the standard cold chain requirement. Mismanagement of cold chain is a leading cause of vaccine failure — a Head Nurse must strictly monitor this.

Volume $V = \frac{\pi d^2 h}{4} = \frac{\pi \times 12.6^2 \times 34.2}{4} \approx 4262.2 \text{ cm}^3$.

Since inputs have 3 significant figures, $V \approx 4260 \text{ cm}^3$.

Error calculation: $\frac{\Delta V}{V} = 2\frac{\Delta d}{d} + \frac{\Delta h}{h}$

$\Delta V = 4260 \left( 2 \frac{0.1}{12.6} + \frac{0.1}{34.2} \right) \approx 4260 (0.01587 + 0.00292) \approx 80 \text{ cm}^3$.

Final value: $4260 \pm 80 \text{ cm}^3$.

Option B ($23.71) is correct.

Labour hours = $240,000 ÷ $4 = 60,000 hours

Fixed production overhead = 60,000 × $10 = $600,000

Total production cost = $298,000 + $240,000 + $600,000 = $1,138,000

Absorption cost per unit = $1,138,000 ÷ 48,000 = $23.71
