Question:
There are two basic types of glaciers, those that flow
outward in all directions with little regard for any underlying terrain and
those that are confined by terrain to a particular path.
The first category of glaciers includes those massive
blankets that cover whole continents, appropriately called ice sheets. There
must be over 50,000 square kilometers of land covered with ice for the glacier
to qualify as an ice sheet. When portions of an ice sheet spread out over the
ocean, they form ice shelves.
About 20,000 years ago the Cordilleran Ice Sheet covered
nearly all the mountains in southern Alaska, western Canada, and the western
United States. It was about 3 kilometers deep at its thickest point in northern
Alberta. Now there are only two sheets left on Earth, those covering Greenland
and Antarctica.
Any domelike body of ice that also flows out in all
directions but covers less than 50,000 square kilometers is called an ice cap.
Although ice caps are rare nowadays, there are a number in northeastern Canada,
on Baffin Island, and on the Queen Elizabeth Islands.
The second category of glaciers includes those of a variety
of shapes and sizes generally called mountain or alpine glaciers. Mountain
glaciers are typically identified by the landform that controls their flow. One
form of mountain glacier that resembles an ice cap in that it flows outward in
several directions is called an ice field. The difference between an ice field
and an ice cap is subtle. Essentially, the flow of an ice field is somewhat
controlled by surrounding terrain and thus does not have the domelike shape of
a cap. There are several ice fields in the Wrangell. St. Elias, and Chugach
mountains of Alaska and northern British Columbia.
Less spectacular than large ice fields are the most common
types of mountain glaciers: the cirque and valley glaciers. Cirque glaciers are
found in depressions in the surface of the land and have a characteristic
circular shape. The ice of valley glaciers, bound by terrain, flows down
valleys, curves around their corners, and falls over cliffs.

characteristic circular shape.
Jawab : B → They
cover large areas of land.
Pembahasan : Frasa whole continents pada kalimat those
massive blankets that cover whole continents appropriately called ice sheet
menunjukkan bahwa daratan yang tertutup gletser mencakup wilayah yang sangat
luas, hampir keseluruhan daratan.

entire continent
(B) buried within the
mountains
(C) spreading into
the ocean
(D) filling deep
valleys
Jawab : C → spreading
into the ocean
Pembahasan : Jawaban
dapat ditemukan pada kalimat terakhir paragraf kedua bahwa jika ice sheet
tersebar (spread out) di lautan akan terbentuk ice shelves.
4. According to the passage, where was the Cordilleran Ice
Sheet thickest?
(A) Alaska
(B) Greenland
(C) Alberta
(D) Antarctica
Jawab : C → Alberta
Pembahasan : Jawaban dapat ditemukan pada baris ke-8: it was
about 3 kilometers deep at its thickest point in northern Alberta.

(A) small
(B) unusual
(C) valuable
(D) widespread
Jawab : B → unusual
Pembahasan : Rare
berarti jarang atau tidak biasa ditemukan sehingga jawaban yang paling
mendekati arti dari rare adalah unusual.

(B) Their flow
(C) Their texture
(D) Their location
Jawab : B → Their flow
Pembahasan : Kalimat Mountain glaciers are typically
identified by the landform that controls their flow dan dijelaskan lebih lanjut
pada kalimat One form of mountain glacier that resembles an ice cap in that it
flows outward in several directions is called an ice field menunjukkan bahwa
pembentukan ice caps dipengaruhi oleh alirannya (their flow).
7. The word “it” in line 16 refers to
(A) glacier
(B) cap
(C) difference
(D) terrain
Jawab : A → glacier

(B) common
(C) important
(D) measurable
Jawab : A → slight
Pembahasan : Padanan
kata subtle adalah slight yang keduanya memiliki arti “tipis, halus, atau
sedikit”.
9. All of the following are alpine glaciers EXCEPT
(A) cirque glaciers
(B) ice caps
(C) valley glaciers
(D) ice fields
Jawab : B → ice caps
Pembahasan : Jenis
alpine/mountain glacier adalah ice fields, cirque glaciers dan valley glaciers
yang semuanya dipengaruhi oleh aliran dan tidak memiliki domelike cap seperti
ice caps.

use to illustrate the two basic types of glaciers mentioned in line 1?
(A) Ice fields and
cirques
(B) Cirques and
alpine glaciers
(C) Ice sheets and
ice shelves
(D) Ice sheets and
mountain glaciers
Jawab : D → Ice sheets and mountain glaciers
Pembahasan : Ada dua jenis gletser yaitu ice sheet yang
mengalir keluar ke segala arah dan mountain glacier yang arah alirannya
terbatas hanya di aliran tertentu.
