Question

A newer and safer alternatives is on the way. Eyedrops can shrink cataracts in dogs, which may prove a first step toward a drug that can treat or even prevent cataracts in human eyes, researchers say.

Cataracts from when the eyes lens grows cloudy, a condition that affects millions of people and accounts for more than half of all cases of blindness worldwide. Currently, the only treatment for cataracts is surgical removal of the clouded lenses. Aging populations around the world are predicted to require adoubling in the number of cataracts surgeries in the next 20 years.

Cataracts often result from clumping of the proteins that make up the lens. To learn more about how eyes normally prevent such clumping and keep lenses transparent, scientists analyzed the genes of two related families that both often suffered cataracts from birth.

To examine what effects lanosterol might have on cataracts, scientists experimented on dogs with naturally occurring cataracts. 

"There are many old dogs with cataracts;' said study co-author Kang Zhang, an ophthalmologist at the University of California, San Diego in La Jolla. "Our collaborators in China had them for another project in cataract research, and we then treated these dogs with lanosterol.”

After six weeks of treatment with lanosterol eyedrops, lens cloudiness and cataract size decreased in the dogs. Similar results were seen in experiments with human lens cells and rabit lenses on lab dishes, "The most important implication is that we can treat cataracts with an eyedrop, not surgery, "Zhang told Live Science. 

Still, "this is a preliminary study, and it needs further work and more studies, as well as confirmation by other researchers;' Zhang cautioned, "We will study the safety of this compound, and plan human trials for treatment of cataracts.”

The paragraph preceding the passage most likely discusses .. .. 
A. A different and more conventional cataract cure 
B. A different kind of eye diseases that resembles cataracts 
C. Patented remedies for eye diseases other than cataracts 
D. The causes and symptoms of cataracts mostly found 
E. New cures for cataracts not yet issued to public

Hai Dodi, kakak bantu jawab ya.

Jawaban dari soal ini adalah:
A. A different and more conventional cataract cure (Obat katarak yang berbeda dan lebih konvensional)

Dalam soal ini, kamu diminta untuk menjawab pertanyaan berdasarkan informasi yang kamu temukan dalam teks bacaan.

Pertanyaannya yakni, "The paragraph preceding the passage most likely discusses ...." yang artinya, "Paragraf yang mendahului teks tersebut kemungkinan besar membahas .....".

Mari kita lihat paragraf 1 teks tersebut: 
"A newer and safer alternatives is on the way. Eyedrops can shrink cataracts in dogs, which may prove a first step toward a drug that can treat or even prevent cataracts in human eyes."

Terjemahan:
Alternatif yang lebih baru dan lebih aman sedang dalam perjalanan. Obat tetes mata dapat mengecilkan katarak pada anjing, yang mungkin membuktikan langkah pertama menuju obat yang dapat mengobati atau bahkan mencegah katarak pada mata manusia, kata para peneliti."

Paragraf 1 membahas mengenai penemuan alternatif pengobatan katarak yang lebih baru dan aman sehingga paragraf pendahulu teks tersebut kemungkinan membahas jenis-jenis pengobatan katarak yang lebih konvensional.

Oleh karena itu, jawaban yang benar adalah "A. A different and more conventional cataract cure".

Semoga membantu ya.
