Directions (1-10): Read the following passage carefully and answer the questions given below it. Certain words have been printed in bold to help you locate them, while answering some of the questions.
Did you know: The air inside your home is actually 2 to 5 times more polluted and toxic than the air you breathe outdoors? It’s appalling, really. We go for regular health check-ups, pop pills on a daily basis, stress over allergies, but neglect the most basic thing there is – the quality of the air we breathe 24/7. Everything from the mattresses we sleep on to our kids’ pajamas can contain harmful chemicals and toxins. Dr. Manoj K. Ahuja, Healing Touch Hospital says, “Breathing in toxic gases can cause rashes, coughing, irritation in the eyes, as well as asthma like symptoms.
Formaldehyde, a toxic gas, is found in insecticides, glues, shampoos, shaving creams, carpets and is actually a carcinogen. It is even found in cigarette smoke which is a major contributor to air pollution and can lead to potentially fatal complications, even if it’s secondhand smoke. Also, chemicals from paint, woodwork in the house or office, hair and nail products, cleaning products and detergents – all contribute to air pollution inside our homes. It surprises me how so many potentially harmful contaminants get trapped inside our homes, and we can’t even open a window to get some fresh air!
During those barren winter months, with windows overlooking long dead gardens, leafless trees, and lawns that seem to have an ashy look about them, nothing soothes the jangled nerves more than the vibrant green of plants surrounding the living spaces of one’s home. People browse through garden stores just to get a whiff of chlorophyll and to choose a plant or two to bring spring back into their winter-gray lives.
Now there is even more of a need for “the green,” in light of recent articles warning us of the hazards of chemicals that we, ourselves, introduce into our homes. Each time we bring clothes home from the cleaners, we release those chemicals into the closed-in air of our dwellings. Every cleanser releases its own assortment of fumes. Some of the chemicals are formaldehyde, chlorine, benzene, styrene, etc. Read the labels on many home products, the ingredients aren’t even listed! During the winter, when those same windows are shut tight, we breathe in these chemicals—causing symptoms much like allergies. In fact, most people probably dismiss the effects of these chemicals simply as a flare up of some allergy or other. The truth is that we are experiencing a syndrome that is called Multiple Chemical Sensitivity. Now, what has this got to do with green plants? Everything healthy! Research has been conducted with two types of plants that have actually removed much of these harmful chemicals from the air.
The two plants that seem to be the best bet for ridding one’s home of such chemicals are ferns and palms. These plants release moisture as part of photosynthesis and, as they do, pull chemicals from the air into their leaves. Even NASA has conducted some greenhouse experiments for long-term space exploration. Within hours, their plants [palms] had removed almost all traces of formaldehyde in the room. Both species of plants are ancient, dating back more than a hundred million years. Another trait they share is that they both live long lives, 100 years or more. This we expect from trees, but ferns and palms are plants; plants that can grow to 65 feet in the proper setting! Even their individual leaves live for one to two years [ferns] and one to nine years [palms]. Perhaps it is their primal qualities that have contributed to their ability to purify their environment.
Q1. What is the main idea of the passage?
(a) Our homes are full of contaminants.
(b) Our allergies are caused by chemicals found in the home.
(c) All plants release moisture in the home.
(d) Certain plants can purify the home of many harmful chemicals.
(e) None of these
Q2. According to the passage, when a few harmful chemicals combine, they can
(a) cause us to experience allergies.
(b) cause a monumental task for homeowners.
(c) contribute to a syndrome called Multiple Chemical Sensitivity.
(d) contribute to photosynthesis in plants.
(e) None of these
Q3. The passage indicates that research
(a) has only been conducted using specific plants.
(b) has only been conducted by NASA.
(c) has not identified the sources of these chemical impurities.
(d) has only benefited long term space exploration.
(e) None of these
Q4. The passage infers a relationship between the antiquity of ferns and palms and their ability to
(a) live long.
(b) purify the air.
(c) grow leaves that live long.
(d) react successfully in research experiments.
(e) None of these
Q5. A good title for this passage is
(a) Research in the New Millennium.
(b) Home Dangers.
(c) Common Houseplants May Purify Your Home.
(d) NASA Experiment Finds the Cure.
(e) None of these
Directions (6 – 8): Choose the word which is most nearly the same in meaning to the word given in bold as used in the passage.
Directions (9 – 10): Choose the word which is opposite in meaning to the word given in bold as used in the passage.
This answer is broad enough to support all the information discussed in the passage: chemicals in the home, research on certain houseplants, the suggestion of the best plants for the job and why. Choice (a) only deals with contaminants. Choice (b) suggests our allergies are caused by chemicals in the home, when the passage suggests that we unknowingly blame our symptoms on allergies. Choice (c) suggests that the passage is only about plants in the home.
This is explicitly stated in the passage. Choice (a) is an incorrect assumption, as the passage does not discuss allergies; it states that we dismiss the symptoms, blaming allergies as the cause. Choice (b) is tempting, but it is not a specific effect of the chemicals combining; it merely states that ridding our homes of impurities seems a great task. Choice (d) is incorrect because the combination of harmful chemicals does not trigger the process of photosynthesis in any way.
It is clearly stated that research has been done using certain houseplants. Choice (b) is incorrect because the sentence that deals with NASA suggests that even NASA is conducting experiments.
Choice (c) reveals a faulty reading of the passage in which three of the chemicals are clearly named. Choice (d) is incorrect because the main idea of the passage is for the benefit of homeowners.
This answer is inferred in the last line of the passage: primal qualities . . . ability to purify their environment. Choices (a) and (c) are incorrect because antiquity refers to how long the species has been on the planet, which has no relationship to how long a life span the individual plants or leaves have. Choice (d) is incorrect. One cannot make a general statement on how successful the plants’ reactions are in research experiments when the passage only presents us with one type of research experiment.
. This title focuses on the main idea of the passage: purifying one’s home of chemical impurities by using common houseplants. Choice (a) is incorrect because only one experiment is discussed, and no mention of the millennium is made at all. Choice (b) is also incorrect because the passage only discusses
one problem: impurities caused by chemicals, which is not even labeled as a danger. Choice (d) is supported by two sentences in the passage, but it is not broad enough to support all the information offered in the passage.
Ashy means shitty, broke, tired, dirty, old, gay, busted, etc… Lurid means unpleasantly bright in colour, especially so as to create a harsh or unnatural effect.
Appalling means horrifying; shocking. Ghastly means causing great horror or fear
Assortment means a miscellaneous collection of things or people. Mélange means a varied mixture.
Allergies means a damaging immune response by the body to a substance, especially a particular food, pollen, fur, or dust, to which it has become hypersensitive. Affinity means a natural liking for and understanding of someone or something.
Trait means a distinguishing quality or characteristic, typically one belonging to a person. Usualness means commonly encountered, experienced, or observed
