Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the
correct answer to each of the questions from 31 to 35.
Nanotechnology is the creation and use of materials or devices at extremely small scales. These
materials or devices fall in the range of 1 to 100 nanometers (nm). One nm is equal to one-billionth of
a meter (. 000000001 m), which is about 50, 000 times smaller than the diameter of a human hair.
Scientists refer to the dimensional range of 1 to 100 nm as the nanoscale, and materials at this scale are
called nanocrystals or nanomaterials.
The nanoscale is unique because nothing solid can be made any smaller. It is also unique because
many of the mechanisms of the biological and physical world operate on length scales from 0. 1 to 100
nm. At these dimensions materials exhibit different physical properties; thus scientists expect that
many novel effects at the nanoscale will be discovered and used for breakthrough technologies.


A number of important breakthroughs have already occurred in nanotechnology. These developments
are found in products used throughout the world. Some examples are catalytic converters in
automobiles that help remove air pollutants, devices in computers that read from and write to the hard
disk, certain sunscreens and cosmetics that transparently block harmful radiation from the Sun, and
special coatings for sports clothes and gear that help improve the gear and possibly enhance the
athlete’s performance. Still, many scientists, engineers, and technologists believe they have only
scratched the surface of nanotechnology’s potential.
Nanotechnology is in its infancy, and no one can predict with accuracy what will result from the full
flowering of the field over the next several decades. Many scientists believe it can be said with
confidence, however, that nanotechnology will have a major impact on medicine and health care;
energy production and conservation; environmental cleanup and protection; electronics, computers,
and sensors; and world security and defense.
(Adapted from: Encarta DVD 2009)

A. causing a chemical reaction to happen faster
B. being different from anything known before
C. being important enough to be noticed
D. being the only one of its kind
Question 34: Which of the following statements is NOT true about nanotechnology according to the
passage?
A. No other products are smaller than those made by nanotechnology.
B. Nanotechnology allows the production of things at extremely small scales.
C. Nanotechnology has seen a number of important breakthroughs.

Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the
correct answer to each of the questions from 36 to 42
To quote CREST founder Dr. Martha Honey, we earnestly believe that ecotourism is “simply a better
way to travel. ” Here’s a look at how this transformational approach to travel benefits conservation,

increases cross-cultural understanding, and ultimately turns travelers into environmental advocates:
To see how ecotourism benefits nature and wildlife, let’s look at endangered species such as African
Elephants. Ivory from Elephant tusks is worth $1500 a pound on the black market, which has led to a
dramatic increase in poaching. But Elephants are worth 76 times more alive than dead. When you
consider the revenue from wildlife photography tours, luxury safari camps, and other ecotourism
offerings, a single Elephant is worth $1. 3 million over the course of its lifetime! Ecotourism offers a
long-term alternative to exploitation, generating sustainable revenue and ensuring better overall health
of the ecosystem.
Nature reserves and national parks help prevent deforestation and pollution, while also protecting the
habitat of endemic species. The revenue that ecotourism provides can help replace profits from
exploitative practices such as mining or slash ‘n’ burn agriculture. It can also help ensure the long-term
financial viability of the area. Naturalist guides also help travelers understand the value of a pristine
ecosystem, and teach them about the importance of conservation. This ultimately help to create a more
mindful and conscious legion of travelers.
When managed properly, ecotourism can offer locals alternative revenue streams. In wildlife-rich
countries such as Rwanda, former poachers are often employed as guides or trackers, capitalizing on
their knowledge of the animals and their habitat. In Costa Rica, unemployment has fallen to less than
10% since the country started building its ecotourism infrastructure in the 1970s. Involving local
communities in tourism management empowers them by ensuring that more revenue is reinvested


locally. Ecotourism also offers indigenous peoples an opportunity to remain on ancestral land,
conserve it, and preserve traditional culture.
Sure, being a responsible traveler takes a greater level of commitment to being conscious and mindful
of the impact we have on the destinations we visit. But ecotourism also offers us incredible,
transformative experiences, allowing us to develop closer personal relationships to the nature, wildlife,
and local people we encounter during our adventures. Learning about ecotourism can permanently
change your understanding of mankind’s role in our planetary ecosystem. And once you’ve had that
sort of travel experience, you’ll never want to travel the traditional way again.

The nanoscale is unique because nothing solid can be made any smaller. It is also unique because
many of the mechanisms of the biological and physical world operate on length scales from 0. 1 to 100
nm. At these dimensions materials exhibit different physical properties; thus scientists expect that
many novel effects at the nanoscale will be discovered and used for breakthrough technologies.
A number of important breakthroughs have already occurred in nanotechnology. These developments
are found in products used throughout the world. Some examples are catalytic converters in
automobiles that help remove air pollutants, devices in computers that read from and write to the hard
disk, certain sunscreens and cosmetics that transparently block harmful radiation from the Sun, and
special coatings for sports clothes and gear that help improve the gear and possibly enhance the
athlete’s performance. Still, many scientists, engineers, and technologists believe they have only
scratched the surface of nanotechnology’s potential.
Nanotechnology is in its infancy, and no one can predict with accuracy what will result from the full
flowering of the field over the next several decades. Many scientists believe it can be said with

confidence, however, that nanotechnology will have a major impact on medicine and health care;
energy production and conservation; environmental cleanup and protection; electronics, computers,
and sensors; and world security and defense.

Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the
correct answer to each of the questions from 36 to 42
To quote CREST founder Dr. Martha Honey, we earnestly believe that ecotourism is “simply a better
way to travel. ” Here’s a look at how this transformational approach to travel benefits conservation,
increases cross-cultural understanding, and ultimately turns travelers into environmental advocates:
To see how ecotourism benefits nature and wildlife, let’s look at endangered species such as African
Elephants. Ivory from Elephant tusks is worth $1500 a pound on the black market, which has led to a
dramatic increase in poaching. But Elephants are worth 76 times more alive than dead. When you
consider the revenue from wildlife photography tours, luxury safari camps, and other ecotourism
offerings, a single Elephant is worth $1. 3 million over the course of its lifetime! Ecotourism offers a
long-term alternative to exploitation, generating sustainable revenue and ensuring better overall health
of the ecosystem.
Nature reserves and national parks help prevent deforestation and pollution, while also protecting the
habitat of endemic species. The revenue that ecotourism provides can help replace profits from
exploitative practices such as mining or slash ‘n’ burn agriculture. It can also help ensure the long-term
financial viability of the area. Naturalist guides also help travelers understand the value of a pristine
ecosystem, and teach them about the importance of conservation. This ultimately help to create a more
mindful and conscious legion of travelers.
When managed properly, ecotourism can offer locals alternative revenue streams. In wildlife-rich

countries such as Rwanda, former poachers are often employed as guides or trackers, capitalizing on
their knowledge of the animals and their habitat. In Costa Rica, unemployment has fallen to less than
10% since the country started building its ecotourism infrastructure in the 1970s. Involving local


communities in tourism management empowers them by ensuring that more revenue is reinvested
locally. Ecotourism also offers indigenous peoples an opportunity to remain on ancestral land,
conserve it, and preserve traditional culture.
Sure, being a responsible traveler takes a greater level of commitment to being conscious and mindful
of the impact we have on the destinations we visit. But ecotourism also offers us incredible,
transformative experiences, allowing us to develop closer personal relationships to the nature, wildlife,
and local people we encounter during our adventures. Learning about ecotourism can permanently
change your understanding of mankind’s role in our planetary ecosystem. And once you’ve had that
sort of travel experience, you’ll never want to travel the traditional way again.
