3. The question is based on the following text.

Exercise is painful. As the cliché goes, “No pain, no gain.” When the body exerts itself, pumping action out of muscles to tear them down and build their mass, it’s left with a soreness. Doctors, coaches, and mothers all recommend heat for tense sore muscles—warm baths, moist towels, hot-water bottles, or heated pads as thermotherapy techniques. But how exactly does applying this heat help the pain and relax the muscles?

While exercising, the body requires more energy than it can produce through aerobic respiration, or the intake of oxygen. To create enough energy for vigorous movement, the body goes through another process: anaerobic respiration. This type of energy production burns sugars without oxygen, producing lactic acid within exerted muscles. Overworked muscles and a buildup of lactic acid are what cause the pain associated with exercising. When heat is applied to a sore area of the body, blood vessels widen and blood flow increases to transport excess lactic acid and other toxins away from tired muscles. These muscles are also made more elastic by the heat, and nerve endings are stimulated to block pain signals.

What is the purpose of the underlined sentence in paragraph 1?

a. highlight the process of muscle building during exercise

b. illustrate the cliché related to exercise and pain

c. explain the sources of pain while exercising

d. show the process of soreness on muscles

e. define the cliché “No pain, no gain”

Jawaban: B

4. Read the text below to answer the question!

A team led by UC Riverside geologists has discovered the first ancestor on the family tree that contains most familiar animals today, including humans. The tiny, wormlike creature, named Ikaria wariootia, is the earliest bilaterian, or organism with a front and back, two symmetrical sides, and openings at either end connected by a gut. The paper is published today in Proceedings of the National Academy of Sciences.

For 15 years, scientists agreed that fossilized burrows found in 555 million-year-old Ediacaran Period deposits in Nilpena, South Australia, were made by bilaterians. However, there was no sign of the creature that made the burrows, leaving scientists with nothing but speculation. Then, Scott Evans, a recent doctoral graduate from UC Riverside; and Mary Droser, a professor of geology, noticed miniscule, oval impressions near some of these burrows. With funding from a NASA exobiology grant, they used a three-dimensional laser scanner that revealed the regular, consistent shape of a cylindrical body with a distinct head and tail and faintly grooved musculature. The animal ranged between 2-7 millimeters long and about 1-2.5 millimeters wide, with the largest the size and shape of a grain of rice -- just the right size to have made the burrows.

"We thought these animals should have existed during this interval, but always understood they would be difficult to recognize," Evans said. "Once we had the 3D scans, we knew that we had made an important discovery."

What is the main idea of the passage?

a. the descendant on the family tree of familiar animals found in Australia

b. a team led by UC Riverside geologists

c. Australian geologists finding most animals

d. the small ancestor of familiar animals identified in Australia

e. the geologists’ discovery of a worm in Australia

Jawaban: D
