correct answer to each of the questions from 30 to 34.
Market research analysts help companies figure out what to sell, who will buy their products and
services, and how to promote them. They design surveys that are used to help discover potential
customers' preferences. These marketing professionals then train and supervise interviewers who conduct
these surveys online, by telephone, or through interviews with individuals or focus groups.
In addition to taking surveys, market research analysts are responsible for keeping track of client

industry trends and general marketing trends, as well as forecasting these markets to provide companies
with proposals and information of the products, services, promotions and all relevant data to help
management in their marketing decisions.
There are now new tools that analysts can use, such as geofencing, which uses GPS or similar
technology to build a virtual fence around a business and offer targeted advertisements to a customer’s
phone as he or she walks through a store. Eye-tracking, which monitors how your eye travels around a
website, is another technology market research analysts use.
The process of collecting and analysing data is logical and quantifiable; figuring out why target
audiences might be attracted to a particular product is not. This is why some of the most successful
market analysts seem to understand human emotions and psychology as much as they understand logic.

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.
Coral reefs are some of the most diverse ecosystems in the world, housing tens of thousands of
marine species. With their hardened surfaces, corals are sometimes mistaken as being rocks. And, because
they are attached, “taking root” to the seafloor, they are often mistaken for plants. However, unlike rocks,
corals are alive. And unlike plants, corals do not make their own food. Corals are in fact animals.
Appearing as solitary forms in the fossil record more than 400 million years ago, corals are extremely
ancient animals that evolved into modern reef-building forms over the last 25 million years.
Coral reefs are the largest structures on earth of biological origin. Coral reefs are unique and complex
systems. Rivaling old growth forests in longevity of their ecological communities, well-developed reefs
reflect thousands of years of history.
Corals are ancient animals related to jellyfish and anemones. The branch or mound that we often
call “a coral” is actually made up of thousands of tiny animals called polyps. A coral polyp is an
invertebrate that can be no bigger than a pinhead to up to 30 centimeters (1 foot) in diameter. The polyps
extend their tentacles at night to sting and ingest tiny organisms called plankton and other small creatures.
Each polyp has a saclike body and a mouth that is encircled by stinging tentacles. The polyp uses calcium
carbonate (limestone) from seawater to build a hard, cup-shaped skeleton. This skeleton protects the soft,
delicate body of the polyp.
Reefs only occur in shallow areas that are reachable by sunlight because of the relationship between
coral and algae. Various types of microscopic algae, known as Symbiodinium, live inside of the coral,
providing them with food and helping them to grow faster.
There are over 2,500 kinds (species) of corals. About 1,000 are the hard corals that build coral

reefs. Other corals are soft corals. Soft corals have skeletons that are flexible and can bend with the water.
The three main types of coral reefs are fringing reefs, barrier reefs, and coral atolls. The most common
type of reef is the fringing reef. This type of reef grows seaward directly from the shore. They form
borders along the shoreline and surrounding islands. When a fringing reef continues to grow upward from
a volcanic island that has sunk entirely below sea level, an atoll is formed. Atolls are usually circular or
oval in shape, with an open lagoon in the center. Any reef that is called a barrier reef gets its name
because its presence protects the shallow waters along the shore from the open sea. That protection
promotes the survival of many types of sea plant and animal life.
