The major staple foods are rice, wheat, corn and some root vegetables. Rice is eaten mainly in Asia, boiled, steamed, or sometimes made into noodles. eaten in Europe and North America. It is usually ground into flour and made into bread or pasta. Corn has been a staple food for people in South America. It is ground and processed into bread, tortillas, or 10 cornflakes. The most common root vegetables are potatoes. They are eaten as a staple food in various areas from South America to Europe. Yams or taro are also eaten widely in Africa, in tropical areas in Asia and in the Pacific. Root vegetables are usually steamed 15 or boiled, and sometimes mashed before being served.

The world is facing a )- crisis of plastic waste, which is growing daily. The situation in Indonesia is serious, but the country has devised an innovative solution. After China, Indonesia is the world's largest producer of plastic waste that ends up in the sea. Estimates put the combined length of the plastic straws z_dis Caredi daily in the country at 5,000 kilometres. One company has come up with a new idea to Ye duce the use of plastic bags. Instead of plastic, it uses cassava, a root that grows abundantly in the country. It has two main biodegradable and breaks down quickly. advantages. First, it is Second, it is not poisonous and will not harm animals. Unfortunately, cassava bags are twice the price of plastic bags, but if the market for them increases, their price will come down.

(I] Read the following two passages and answer the questions. 資料1 A cave-wall depiction of a pig and buffalo hunt is the world's oldest recorded story, claim archaeologists who discovered the work on the Indonesian island Sulawesi. The scientists say the scene is more than 44,000 years old. The 4.5-metre-long panel features reddish-brown forms that seem to depict human-like figures hunting local animal species. Previously, rock paintings found in European sites dated to around 14,000 to 21,000 years old were considered to be the world's oldest clearly narrative artworks. The scientists working on the latest find say that the Indonesian art predates these. Such artworks are notoriously difficult to date because they can be made with raw materials, such as charcoal(注1), which can be much older than the paintings themselves. But scientists excited the archaeological worid when they reported, in 2014 and 2018, that caves in Sulawesi and Borneo held artworks, including animal paintings, which were older than 40,000 years. The panel seems to depict wild pigs found on Sulawesi and a species of small-bodied buffalo, called an anoa. These appear alongside smaller figures that look human but also have animal traits such as tails and long noses. In one section, an anoa is surrounded by several figures holding spears and possibly ropes. The depiction of these animal-human figures, known in mythology as therianthropes (注 2), suggests that early humans in Sulawesi had the ability to conceive of things that do not exist in the natural world, claim 2 the researchers. The oldest such example from Europe is a half-lion, half-human ivory figure from Germany that researchers have estimated to be 40,000 years old-although Some suggest that it might be significantly younger. A roughly 17,000-year-old painting of a bison chasinga bird-headed human, from Lascaux Cave in France, is considered to be one of the earliest depictions of a clear scene in European rock art. To determine the age of the hunting scene, researchers led by archaeologist Maxime Aubert, at Griffith University, Australia, analysed calcite (注 3) 'popcorn' that had built up on the painting. Radioactive uranium in the mineral slowly decays into thorium. So by measuring the relative levels of different isotopes (往0 of these elements, the researchers were able to determine that calcite on top of one pig began forming at least 43,900 years ago, and deposits (注 5) on two anoas are older than 40,900 years. The dating gives scientists clues about the origins of figurative art. "t has always been assumed that the tradition of figurative painting arose in Europe," says Alistair Pike, an archaeological scientist at the University of Southampton, UK. "This shows the tradition does not have its origins in Europe." But he notes that the researchers dated only the portions of the painting that show animals, so it's possible that the therianthropes were added later. Aubert says the team did not find calcite samples over the therianthropes. Aubert thinks the animals and the therianthropes were painted at the same time. They are of similar colour and weathered in the same way, he notes, and all the other cave art from the region is from the same time period. Archacologist Bruno David, at Monash University in Melbourne, Australia, agrees with Aubert's interpretation. If the entire painting is more than 44,000 years olid, it could mean that early humans arrived in southeast Asia with the capacity for symbolic representation and storytelling. David argues. Archaeologists have already found paint palettes and objects such as eggshells with abstract engravings made by early humans in southern Africa, he adds. “'s probably only a matter of time before narrative paintings of this, and much older age, are found in Africa."
