Lack of calcium does not directly result in anaemia. Anaemia is a condition caused by a deficiency of red blood cells or hemoglobin in the blood. Calcium deficiency can lead to other health issues such as weak bones, muscle cramps, or osteoporosis, but it does not directly cause anaemia.

Explanation
Fresh fish can be identified by scales clinging to the body. This is because scales are an important characteristic of fish and they are present on the skin. When a fish is fresh, the scales will be intact and firmly attached to the body. On the other hand, if the fish is not fresh, the scales may start to loosen or fall off. Therefore, the presence of scales clinging to the body indicates that the fish is fresh.

Explanation
Charcoal is more economical to use in rural areas because it is readily available and can be produced locally at a lower cost compared to electricity and kerosene. In rural areas, access to electricity may be limited or unreliable, and the cost of installing and maintaining electrical infrastructure can be expensive. Kerosene, on the other hand, needs to be purchased and transported, which can be costly in remote areas. Charcoal, however, can be easily produced from locally available biomass, such as wood, and is a cheaper alternative for cooking and heating purposes in rural areas.

Explanation
Cooking food by convection in an enclosed space is termed as baking. Baking typically refers to the process of cooking food in an oven, where heat is circulated through the oven by convection. This method is commonly used for cooking bread, cakes, pastries, and other baked goods. It involves surrounding the food with hot air, allowing it to cook evenly and develop a golden crust. Baking is different from microwave cooking, which uses electromagnetic waves to heat the food, and roasting, which typically involves cooking meat or vegetables at high temperatures in an open space.

Explanation
Shallow frying is the best method of cooking for pancakes because it allows for even cooking and a crispy exterior while maintaining a soft and fluffy interior. Deep frying would result in an overly greasy and heavy pancake, while pressure cooking would not provide the desired texture and browning. Shallow frying allows the pancake batter to spread evenly on the pan, creating a golden brown crust and a light and airy pancake.

Explanation
When rice is cooked by boiling, the water used is absorbed by the rice. This is because rice grains have the ability to absorb water and swell up during the cooking process. As the rice cooks, the starches in the grains absorb the water, which helps to soften and cook the rice evenly. Once the rice is fully cooked, most of the water has been absorbed, resulting in fluffy and tender rice grains. Therefore, the correct answer is that the water used is absorbed.

Explanation
Body measurement is crucial in making a garment fit properly. By accurately measuring the body, the designer or tailor can create a garment that conforms to the individual's unique shape and size. This ensures that the garment will not be too loose or too tight, providing the wearer with comfort and ease of movement. Without proper body measurement, the garment may not fit well, leading to discomfort and dissatisfaction for the wearer.

Explanation
The spool pin of a sewing machine is used for preventing the thread from twisting. This is because the spool pin holds the spool of thread in place and allows it to rotate smoothly, ensuring that the thread unwinds evenly without tangling or twisting. By keeping the thread straight and untwisted, it allows for a smoother sewing process and prevents any potential issues or disruptions in the stitching.
