Explanation
Ink is an ancient Egypt invention. The Egyptians developed a form of ink made from a mixture of carbon black, gum, and water. They used this ink to write on papyrus, a type of paper made from reeds that grew along the Nile River. The invention of ink was significant because it allowed the Egyptians to record and preserve information, such as religious texts, historical events, and administrative records. Ink was an essential tool for scribes and played a crucial role in the development of writing and literacy in ancient Egypt.

A shadoof is a water lifting device used in ancient civilizations, particularly in Egypt. It consists of a long wooden beam with a counterweight on one end and a bucket or container on the other end. By pulling down on the counterweight, the bucket is lowered into a water source such as a river or well. When the counterweight is released, the bucket is lifted, allowing the water to be transported to higher ground for irrigation or other purposes. This simple yet effective device played a crucial role in agriculture and water management in ancient times.

Explanation
Ancient Egyptians made paint brushes with reeds. Reeds were widely available in the Nile River, which made them a convenient and accessible material for creating paint brushes. The reeds were likely cut and shaped to form a brush-like tip, allowing the Egyptians to apply paint to various surfaces for artistic and decorative purposes. The use of reeds as paint brushes showcases the resourcefulness and creativity of the ancient Egyptians in utilizing natural materials for their artistic endeavors.

Explanation
Soot and vegetable gum and water were used to make ink. Soot, which is a black, powdery substance produced by burning organic matter, provided the color pigment for the ink. Vegetable gum, a sticky substance derived from plants, acted as a binder to hold the pigment together and adhere it to the writing surface. Water was added to the mixture to achieve the desired consistency and to help dissolve the gum and distribute the pigment evenly. This combination of ingredients created a functional ink that could be used for writing or drawing purposes.

Explanation
The correct answer is a bowl and spoon. Grinding up herbs requires a tool that can crush and mix the herbs effectively. A rock may be too rough and uneven, making it difficult to grind the herbs properly. A stick may not have the necessary flat surface to crush the herbs effectively. On the other hand, a bowl and spoon provide a smooth and flat surface that allows for efficient grinding and mixing of the herbs.

Explanation
Fig is the correct answer because it has been traditionally used as a natural remedy for diarrhea. Figs are high in dietary fiber, which helps regulate bowel movements and prevent loose stools. They also contain natural enzymes that aid in digestion and soothe the digestive system. Additionally, figs have a high water content, which helps prevent dehydration caused by diarrhea. Therefore, consuming figs can help alleviate symptoms and promote recovery from diarrhea.
