BASIC DRILLS

Read the paragraphs and answer the questions. Each question asks you to use a context clue to
help you find the meaning of the highlighted word.

01

Animals and insects possess good ultrasonic hearing that allows them to hear what
humans cannot. Bats use ultrasounds, with frequencies ranging from 100 kHz and 200 kHz
to navigate in the darkness and detect their prey. Similarly, toothed whales like dolphins
use ultrasonic hearing in their navigational system to find and capture prey. Among the
same species, porpoises are known to have the highest hearing capacity at around 160 kHz.
Dogs can also hear sounds in the upper audible range of humans, so a dog whistle, which
emits high-frequency sounds, is used to call to dogs in their training.

The word detect in the paragraph is closest in meaning to

A locate
B test
C attract
D lighten

02

The time before significant European influence on the cultures of the America is known as
the pre-Columbian era. While it is literally referred to as the period preceding Christopher
Columbus’s exploration in 1492, the term pre-Columbian in practice includes decades and
even centuries after the discovery of the American continents, during which indigenous
cultures continued to develop. Asian nomads are thought to be the first to enter the
Americas, crossing the Bering Land Bridge via watercraft along the Northwest coast. The
theory of multiple genetic populations of Asiatic migration is supported by evidence found
in mitochondrial DNA of the indigenous peoples of the Americas.
