Whales are hunted primarily for their meat and oil. In some cultures, whale meat is considered a delicacy and is consumed as a source of protein. Whale oil, on the other hand, has historically been used for various purposes such as fuel for lamps, lubricants, and in the production of cosmetics and soaps. These valuable resources drive the hunting of whales, resulting in their decline and endangerment.

The correct answer is "Illegal Hunting". This is because illegal hunting is one of the main reasons why animals become endangered. Many animals are hunted for their valuable body parts, such as ivory, fur, or horns, which leads to a decline in their population. This activity is illegal and unsustainable, causing a significant threat to various species and their habitats.

Antarctica is the correct answer. It is the continent located in the southernmost part of the world and is home to the South Pole. It is known for its vast ice sheet, which is the largest single mass of ice on Earth.

The Sumerians, who inhabited Mesopotamia (modern-day Iraq) around 3500 BCE, developed cuneiform, the earliest known writing system. Cuneiform used wedge-shaped marks pressed into clay tablets to represent words and symbols. This invention revolutionized communication and record-keeping, paving the way for the development of written language in other civilizations.

The given answer is supported by the statements in the question that mention transportation issues existing worldwide. The statement "There are always transportation issues over the world" implies that transportation problems are a common occurrence globally. This suggests that transportation issues are not limited to specific countries or regions, but rather a widespread phenomenon.

An endangered species refers to any species that is at risk of becoming extinct throughout all or a significant portion of its range. This means that the population of the species is declining rapidly, and if no conservation measures are taken, it may cease to exist in the near future. This category is used to identify species that are in immediate danger and require urgent protection and conservation efforts to ensure their survival.

The correct answer is "All above." This answer is correct because the statement in the question states that transportation caused many problems, and it lists three specific problems: public noise, atmospheric pollution, and parking difficulties. Therefore, all of the options listed in the question are valid examples of problems caused by transportation.

B is correct because a diary written by an ancient Egyptian is a primary source, providing direct, firsthand evidence of the past. Textbooks, newspaper articles, and documentary films are secondary sources, as they interpret and summarize information from primary sources.

The correct answer is 12 countries. The Antarctic Treaty, signed in 1961, was an international agreement that aimed to preserve Antarctica for peaceful purposes and scientific research. It was initially signed by 12 countries, including the United States, the Soviet Union, and the United Kingdom, among others. The treaty set aside territorial claims and prohibited military activity, ensuring that Antarctica would be used exclusively for peaceful and scientific purposes. This agreement marked a significant step towards international cooperation and environmental protection in the region.

The correct answer is 46 because the agreement that was signed in 1961 has been signed by more countries now. This implies that the number of countries involved in the agreement has increased over time.
