Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the best answer to each of the following questions from 31 to 40.

Biting into a ripe, juicy fruit brings a smile to many people’s faces. But eating that same fruit a week before it is ripe probably wouldn’t be as enjoyable! Unripe fruits are often hard and bitter, but that serves a purpose. The hard exterior of an unripe fruit protects the developing seed inside. After a seed fully develops inside the fruit, the fruit changes color, softens, and gets sweeter to become more attractive to animals and humans. These organisms eat the fruit and spread its seeds, ensuring the plant’s survival and regrowth.

But how does a fruit ripen? The ripening process involves many complex chemical reactions. When a fruit ripens, it goes through a chemical change. A chemical change happens when bonds within molecules break, and the atoms that once formed them regroup into new molecules. Chemical changes are irreversible. Once a fruit ripens, it cannot become unripe again.

One molecule responsible for this chemical change is ethylene. Ethylene (C2H4) is a colorless gas made up of carbon and hydrogen atoms. (I). It is a naturally occurring molecule in the atmosphere. (II). It is also an important plant hormone. (III). Plants release ethylene through the growing tips of roots, flowers, and ripening fruit. (IV). Although ethylene serves other purposes in plants, one of its main purposes is to trigger the chemical reactions that cause fruits to ripen. As the fruit matures, oxygen in the air helps stimulate the production of ethylene. This ethylene production is a signal that begins fruit ripening. For that reason, unripe fruits have low levels of ethylene, while ripe fruits have higher levels of ethylene. Most fruits produce ethylene and respond to ethylene in the atmosphere.

Although fruits require ethylene to ripen, different types of fruits respond to this molecule in two distinct ways: non-climacteric fruits and climacteric fruits. Non-climacteric fruits do not ripen after harvesting. They produce very little ethylene of their own. Climacteric fruits, on the other hand, continue to ripen after they are picked. These fruits produce a large amount of ethylene. Climacteric fruits can also speed up the ripening process of other fruits nearby since they release high levels of ethylene into the air.  

Which of the following best paraphrases the underlined sentence: The ripening process involves many complex chemical reactions.

Read the following passage about Healthy Benefits of Yoga and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questions from 23 to 30.

Yoga is a healthy lifestyle. One of the benefits of yoga is that you can choose a yoga style that is suitable for your lifestyle, such as hot yoga, power yoga, relaxation yoga, etc. If you are a yoga beginner, Hatha Yoga, which focuses on basic postures at a comfortable pace, would be great for you. If you want to increase strength through using more of your own body’s resistance, Power Yoga may be right for you. Whether you prefer you're at home, in a private session, watching a DVD or at a studio or gym, there are a huge variety of options available to suit your goals and needs.

Improved flexibility is one of the first and most obvious benefits of yoga.  During your first class, you probably won’t be able to touch your toes. But if you stick with it, you’ll notice a gradual loosening, and eventually, seemingly impossible poses will become possible. Each of the yoga poses is built to reinforce the muscles around the spine, the very center of your body, which is the core from which everything else operates. 

When the core is working properly, posture is improved, thus alleviating back, shoulder, and neck pain. Strong muscles do more than look good.  They also protect us from conditions like arthritis and back pain, and help prevent falls in elderly people. And when you build strength through yoga, you balance it with flexibility. If you just went to the gym and lifted weights, you might build strength at the expense of flexibility.

Yoga gets your blood flowing. More specifically, the relaxation exercises you learn in yoga can help your circulation, especially in your hands and feet. Yoga also gets more oxygen to your cells, which function better as a result. Twisting poses are thought to wring out venous blood from internal organs and allow oxygenated blood to flow in once the twist is released. Many studies found that a consistent yoga practice improved depression and led to greater levels of happiness and better immune function.

According to the passage, which of the following statements is TRUE?
