TEXT A The tropical rainforest is a forest of tall trees in a region of year-round warmth. An average of 50 to 260 inches (125 to 660 cm) of rain falls yearly. Rainforests now cover less than 6% of Earth's land surface. Scientists estimate that more than half of all the world's plant and animal species live in rainforests. Tropical rainforests produce 40% of Earth's oxygen. A tropical rainforest has more kinds of trees than any other area in the world. Scientists have counted about 100 to 300 species in one 2 1/2 acre (1-hectare) area in South America. Seventy percent of the plants in the rainforest are trees. About 1/4 of all the medicines we use come from rainforest plants. Curare comes from a tropical vine and is used as anesthetic and to relax muscles during surgery. Quinine, from the cinchona tree, is used to treat malaria. A person with lymphocytic leukemia has a 99% chance that the disease will go into decrease because of the rosy periwinkle. More than 1,400 varieties of tropical plants are thought to be potential cures for cancer. Each of the three largest rainforests - the American, the African, and the Asian - has a different group of animal and plant species of the other two rainforests. In addition, different areas of the same rainforest may have different species. Many kinds of trees that grow in the mountains of the Amazon rainforest do not grow in the lowlands of that same forest. TEXT B Though dry forests occur in climates that are warm year-round, and may receive several hundred centimetres of rain per year, they deal with long dry seasons which last several months and vary with geographic location. These seasonal droughts have great impact on all living things in the forest. Deciduous trees predominate these forests, and during the drought a leafless period occurs, which varies with species type. The newly bare trees open up the canopy layer, enabling sunlight to reach ground level and facilitate the growth of thick underbrush. Though less biologically diverse than rain forests, tropical dry forests are still home to a wide variety of wildlife including monkeys,large cats parrots, various rodents, and ground dwelling birds. Many of these species display extraordinary adaptations to the difficult climate. The most diverse dry forests in the world occur in southern Mexico and in the Bolivian lowlands. The dry forests of the Pacific Coast of north western South America support a wealth of unique species due to their isolation. The dry forests of central India and Indochina are notable for their diverse large vertebrate faunas. Dry forests of Madagascar and New Caledonia are also highly distinctive (pronounced endemism and a large number of Relictual taxa) for a wide range of taxa and at higher taxonomic levels. Species tend to have wider ranges than moist forest species, although in some regions many species do display highly restricted ranges; most dry forest species are restricted to tropical dry forests, particularly in plants; beta diversity and a1pha diversity high but typically lower than adjacent moist forests. The theme that best represents the two texts above would be .... A. flora and fauna in different forests in wet and dry lands B. medical prospects of the flora from rain and dry forests C. tropical rain forests as a source of herbal medications D. biodiversity richness of tropical and dry forests E. differences of fauna types in rain and dry forests

Hai Arka, kakak bantu jawab yaa. Jawaban dari soal ini adalah E. differences of fauna types in rain and dry forests. Soal menanyakan tema yang tepat untuk kedua teks di atas. Teks pertama kebanyakan membahas tentang keragaman tanaman dan juga hewan yang ada di hutan hujan tropis. Berikut adalah kalimat-kalimat yang mendukung penjelasan tersebut: 1. Scientists estimate that more than half of all the world's plant and animal species live in rainforests. (Para ilmuwan memperkirakan bahwa lebih dari separuh spesies tumbuhan dan hewan di dunia hidup di hutan hujan.) 2. A tropical rainforest has more kinds of trees than any other area in the world. (Hutan hujan tropis memiliki lebih banyak jenis pohon daripada daerah lain mana pun di dunia.) 3. About 1/4 of all the medicines we use come from rainforest plants. (Sekitar 1/4 dari semua obat yang kami gunakan berasal dari tanaman hutan hujan.) 4. More than 1,400 varieties of tropical plants are thought to be potential cures for cancer. (Lebih dari 1.400 varietas tanaman tropis dianggap berpotensi menyembuhkan kanker.) 5. Each of the three largest rainforests - the American, the African, and the Asian - has a different group of animal and plant species of the other two rainforests. (Masing-masing dari tiga hutan hujan terbesar - Amerika, Afrika, dan Asia - memiliki kelompok spesies hewan dan tumbuhan yang berbeda dari dua hutan hujan lainnya.) Teks kedua kebanyakan membahas tentang keragaman tanaman dan juga hewan yang ada di hutan kering tropis. Berikut adalah kalimat-kalimat yang mendukung penjelasan tersebut: 1. Deciduous trees predominate these forests, and during the drought a leafless period occurs, which varies with species type. The newly bare trees open up the canopy layer, enabling sunlight to reach ground level and facilitate the growth of thick underbrush. (Pohon-pohon gugur mendominasi hutan-hutan ini, dan selama periode tanpa daun terjadi, tanaman bervariasi menurut jenis spesies. Pohon-pohon yang baru gundul membuka lapisan kanopi, memungkinkan sinar matahari mencapai permukaan tanah dan memfasilitasi pertumbuhan semak belukar yang lebat.) 2. Though less biologically diverse than rain forests, tropical dry forests are still home to a wide variety of wildlife including monkeys, large cats parrots, various rodents, and ground dwelling birds. (Meskipun keanekaragaman hayatinya kurang dari hutan hujan, hutan kering tropis masih menjadi rumah bagi berbagai macam satwa liar termasuk monyet, burung beo kucing besar, berbagai hewan pengerat, dan burung yang tinggal di tanah.) 3. The dry forests of the Pacific Coast of north western South America support a wealth of unique species due to their isolation. The dry forests of central India and Indochina are notable for their diverse large vertebrate faunas. Dry forests of Madagascar and New Caledonia are also highly distinctive (pronounced endemism and a large number of Relictual taxa) for a wide range of taxa and at higher taxonomic levels. (Hutan kering di Pantai Pasifik di barat laut Amerika Selatan mendukung kekayaan spesies unik karena keterisolasiannya. Hutan kering di India tengah dan Indochina terkenal karena beragam fauna vertebrata besar mereka. Hutan kering Madagaskar dan Kaledonia Baru juga sangat khas dalam berbagai taksa dan pada tingkat taksonomi yang lebih tinggi.) Teks pertama membahas tentang flora dan fauna di hutan hujan tropis, sedangkan teks kedua membahas tentang flora dan fauna di hutan kering tropis. Maka, jawaban yang paling tepat adalah E. differences of fauna types in rain and dry forests. (perbedaan jenis fauna di hutan hujan dan hutan kering) Semoga membantu.
