Explanation
The correct answer is rickect 3. Rickets is a condition that occurs due to a deficiency of vitamin D, calcium, or phosphate. It leads to weak and soft bones, causing skeletal deformities such as bowed legs. Anemia is a condition characterized by a deficiency of red blood cells or hemoglobin in the blood, which can be caused by various factors but not directly related to calcium deficiency. Goiter is an enlargement of the thyroid gland and is typically caused by iodine deficiency, not calcium deficiency. Therefore, rickets is the correct answer in this context.

Explanation
Charcoal is more economical to use in rural areas because it is readily available and can be produced locally from easily accessible biomass sources such as wood. It is a cheaper fuel option compared to electricity, which requires infrastructure and ongoing costs for maintenance and distribution. Similarly, kerosene is a fossil fuel that needs to be purchased, making it more expensive than charcoal in the long run. Additionally, charcoal can be used for various purposes like cooking and heating, making it a versatile and cost-effective fuel option for rural communities.

Explanation
Baking is the correct answer because it refers to cooking food by convection in an enclosed space. This method typically involves using an oven to cook food by surrounding it with hot air, resulting in even cooking and browning. Baking is commonly used for items like bread, cakes, cookies, and pastries.

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 to cook quickly and evenly in a small amount of oil, resulting in a delicious and perfectly cooked pancake.

Explanation
When rice is cooked by boiling, the water used is absorbed by the rice grains. As the rice cooks, it absorbs the water, which helps to soften and cook the grains. This absorption process allows the rice to become tender and fully cooked. The absorbed water also helps to release the starch in the rice, giving it a sticky texture. Therefore, the correct answer is that the water used in boiling rice is absorbed by the rice grains.

Explanation
Crocheting is a method of creating fabric by using loops. In crocheting, yarn is pulled through loops to create different stitches and patterns. These loops are formed by inserting the crochet hook into the previous loops and pulling the yarn through. By repeating this process, a fabric is created with interlocking loops. Therefore, loops are an essential element in the technique of crocheting.

Explanation
When two or more pieces of fabric are joined together, they are typically sewn using stitches. Stitches are made by looping thread through the fabric to hold the pieces together. Patches are separate pieces of fabric used for decorative purposes or to cover holes, while buttons are small fasteners used to secure fabric together. Therefore, the correct answer is stitches.

Explanation
Fried yam can be packaged in an A4 sheet because it is a solid food item that can easily fit within the dimensions of the sheet. Water, being a liquid, cannot be packaged in a sheet, and cooked yam may not be suitable for packaging in a sheet due to its texture and moisture content. However, fried yam can be neatly arranged and wrapped in a sheet, making it a viable option for packaging.

Explanation
Good stitches are flat and strong because a flat stitch ensures that the fabric lays flat and does not create any bulk or unevenness. This is especially important in sewing projects where the stitches are visible. Additionally, strong stitches are necessary to ensure that the seam or join holds up over time and does not easily come undone. Strong stitches provide durability and longevity to the garment or item being sewn.

Explanation
Patching refers to the process of attaching a piece of fabric onto a worn out portion of an article. This technique is commonly used to repair holes or tears in clothing or other fabric items. It involves sewing or otherwise securing the patch onto the damaged area, providing reinforcement and extending the lifespan of the item. Darning, on the other hand, refers specifically to the technique of repairing holes or worn areas in knitted or woven fabric using a needle and thread. Stitching is a more general term that encompasses various sewing techniques and can refer to any type of sewing or joining of fabric.
