**Solution:** When a person skates on thin ice, the ice can break due to the weight of the person. This is because the pressure exerted by the person on the ice can exceed the strength of the ice. 1. **Understanding Pressure**: Pressure is defined as the force applied per unit area. The formula for pressure (P) is given by: \[ P = \frac{F}{A} \] ...

Question Stimulus DIRECTIONS: Read the following passage carefully and complete the following sentences. A penguin is a water bird that can't fly. It has webbed feet and wings that look like flippers. It uses its wing flippers for underwater swimming. Many penguins live in the icy waters in or near Antarctica. They seldom visit land except to raise their young ones. Penguins have short legs and tall, torpedo-shaped, bodies. On land they are able to stand upright, and because of their stature, they walk with a waddle. They may appear awkward, but penguins actually walk about as fast as people. They also climb rocky shores by hopping from rock to rock. Some penguins travel over ice and snow by ‘tobogganing’ sliding on their bellies. But penguins travel best by swimming, hour after hour. There are 17 species of penguins, ranging in size from the largest emperor penguin to the diminutive fairy penguin. Penguins will not cross warm ocean water; therefore, they are all found in south of the equator. The Galapagos penguin lives in the farthest north, near the equator in the cold waters around the islands of the same name. Penguins are popular around the world, primarily for their unusually upright, waddling gait and (compared to other birds) lack of fear of humans. Their striking black and white plumage is often likened to a tuxedo suit. Which word in the passage means ‘extremely or unusually small'?
