Concept: Hyperacidity drugs were designed after a key discovery about how acid secretion is triggered.

1. The discovery that histamine stimulates the secretion of HCl (and pepsin) in the stomach was the breakthrough.
2. This led to H₂-receptor antagonists such as cimetidine and ranitidine, which block histamine and reduce acid.
3. Older antacids (Mg(OH)₂, NaHCO₃) only neutralised acid; antibiotics do not neutralise acid at all.

Yaad rakhein: Cimetidine/ranitidine = anti-histamine at H₂ receptor of stomach.

Answer: (C) Histamine stimulates acid secretion in the stomach

Concept: The taskbar is the bar (usually at the bottom) of the Windows desktop.

3. Files are stored in folders/drives, not the taskbar; login details are managed by user accounts.

Yaad rakhein: Taskbar = Start + pinned apps + running apps + clock.

Answer: (A) It provides access to open and frequently used programs.

Concept: The Dutch (VOC) traded Coromandel textiles to buy spices in South-East Asia.

1. The Dutch set up factories at Masulipatnam, Pulicat (Fort Geldria) and Nagapattinam on the Coromandel Coast.

Yaad rakhein: Dutch formula: Coromandel cloth → Indonesian spices → Europe.

Answer: (B) an increase in the demand for textile from the south-east Asian markets

Concept: Density is mass per unit volume.

1. $\text{Density}=\frac{\text{Mass}}{\text{Volume}}$, SI unit ${\text{kg/m}}^3$.
2. Weight is a force (mass × g), so weight/volume is weight density, not density.
3. Volume/mass is specific volume (the reciprocal).

Answer: (D) $\text{Density}=\frac{\text{Mass}}{\text{Volume}}$

Concept: Malaria fever comes in cycles because of the parasite's life cycle inside red blood cells.

1. Plasmodium multiplies asexually inside RBCs; the infected RBCs burst together, releasing new merozoites and the toxin haemozoin.
2. This causes chill and high fever, repeating every 48 hours (P. vivax) or 72 hours (P. malariae).
3. Liver stage occurs only once initially and causes no fever cycle.
