Question

The Megatherium is an extinct type of giant ground sloth that lived from two million to perhaps 4,400 years ago. While medium-sized sloths continue to live in arborous habitats in Centtal and South America, the grounddwelling Megatherium lived in parts of North and South America. These animals were as big as elephants and had huge claws on their feet. Evidence suggests three theories that may have contributed to the giant sloth's extinction, which occurred at about the same time as humans arrived on the continent.

The first theory pertaining to the extinction of the giant ground sloth connects its  disappearance with the arrival of humans. The most plausible explanation for this simultaneous action is that humans hunted the giant ground sloth to its extinction. Early humans hunted animals for a variety of reasons, but food and clothing were among the most important. They could eat the animals that they killed and then fashion the skins into clothing. Humans may also have killed animals as perceived threats, even if they were not valuable as a source of food or clothing. Scientists using radiocarbon to date giant sloth fossils from Cuba and Hispaniola recently found  that the last record of a giant ground sloth coincided with the arrival of humans about 4,400 years ago.

The evidence found in favor of the human hunting hypothesis contrasts with a second theory that climate change was the primary reason for the giant ground sloth's extinction. Some scientists think that the giant ground sloth was not able to adapt to the climate changes that followed the last Ice Age, which ended about 10,000 years ago. At the onset of the Ice Age, the Earth's temperature dropped, and ice sheets and glaciers expanded. These changes would have affected the giant ground sloth's eating habits, and evidence has been found to prove that the last surviving giant ground sloths had drastically different eating habits than their immediate predecessors. A third theory has looked at the possibility of a hyper disease leading to the giant ground sloth's extinction. This theory maintains that the giant ground sloth was particularly vulnerable to disease because of its large body size and small population. One suggestion is that the domestic dogs that humans brought with them transmitted pathogens to the giant ground sloth population. Critics of this theory state that it cannot account for several major extinction events that occurred before humans and domestic dogs migrated together. In Australia, for example, domesticated dogs did not arrive until 35,000 years after humans lived on the continent and 30,000 years after the giant ground sloth was believed to be extinct there.

According to passage, the best evidence supporting the human hunting hypothesis is that ...
(A) humans used giant ground sloth skins for clothing
(B) humans relied on a diet of giant ground sloth meat
(C) giant ground sloth bones have been found near human cooking utensils
(D) the last giant ground sloth fossils found coincide with the arrival of humans
(E) humans and dogs hunted together when they migrated into ground sloth habitats

Halo Mawar, kakak bantu jawab ya :)

Jawabannya adalah "(D) the last giant ground sloth fossils found coincide with the arrival of humans".

Soal menanyakan bukti yang mendukung hipotesis perburuan manusia.

Bacaan di atas berisi tentang hewan megatherium, yaitu sejenis kungkang tanah raksasa yang telah punah. Salah satu hipotesis kepunahannya adalah akibat perburuan manusia.

Hipotesis ini bisa dilihat pada awal paragraf 2. Bukti yang digunakan untuk mendukung hipotesis itu disebutkan pada akhir paragraf yaitu "Scientists using radiocarbon to date giant sloth fossils from Cuba and Hispaniola recently found that the last record of a giant ground sloth coincided with the arrival of humans about 4,400 years ago".

Artinya yaitu "Para ilmuwan yang menggunakan radiokarbon untuk mengetahui fosil kungkang raksasa dari Kuba dan Hispaniola baru-baru ini menemukan bahwa catatan terakhir kungkang tanah raksasa bertepatan dengan kedatangan manusia sekitar 4.400 tahun yang lalu".

Oleh karena itu, jawabannya adalah "(D) the last giant ground sloth fossils found coincide with the arrival of humans" (fosil kungkang raksasa terakhir yang ditemukan bertepatan dengan kedatangan manusia).

Semoga membantu ya :)
