● Which statement is not listed as a detail in the passage?
A. The oncoming sound waves have a higher pitch because of high
frequency and closeness of
waves.
B. The oncoming sound waves have a higher pitch because of low
frequency and closeness of
waves.
C. The whistling sound of the locomotive as it approaches and passes
can be explained by the
Doppler effect
D. The high-pitched sound of the ambulance as it approaches and passes
can be explained by
the Doppler effect. Answer: B. The oncoming sound waves have a
higher pitch because of low frequency and closeness of
waves
● What is the main idea of the passage?
A. Trains and ambulances make distinctly loud noises
,B. Low-frequency waves make high-pitched sounds.
C. High-frequency waves make low-pitched sounds.
D. The Doppler Effect explains the rationale for why sound is heard
initially more strongly and
then faintly after a moving object has passed. Answer: D. The Doppler
Effect explains the rationale for why sound is heard initially more
strongly and
then faintly after a moving object has passed
● What is the meaning of the word phenomenon in the second
paragraph?
A. Something that is lifeless to the senses
B. Something that is nonchalant
C. Something that is significant but unusual
D. Something that is chemical in origin. Answer: C. Something that is
significant but unusual
● What is the author's primary purpose in writing this essay?
A. To entertain the reader with information about trains and ambulances
B. To inform the reader about avoiding accidents, which involve trains
and ambulances
C. To inform the reader about how movement affects sound
D. To analyze the difference between train and ambulance sounds.
Answer: C. To inform the reader about how movement affects sound
,● Which sound waves have a higher pitch?
A. Those waves that are closer together
B. Those waves that are farther apart
C. Those waves that travel a long distance
D. Those waves that travel a short distance. Answer: A. Those waves
that are closer together

● Electrocardiogram Beep!...Beep!...Beep! is the audible rhythmic
sound made as the strength of the heart
muscle is measured. The signal cadence has a characteristic record that
varies in every individual. This
record is called an electrocardiogram, or ECG. In the body, an array of
systemic neural responses
constantly occur, emitting electric currents. The electric currents can be
detected on the surface of the
, body, and if a person is hooked to an amplifier, these impulses are
recorded by an electrocardiograph.
Most of the information obtained is about the heart because the heart
sends out electric currents in
waves. This "wave of excitation" spreads through the heart wall and is
accompanied by electric changes.
The wave takes place in three distinct steps. Initially, the "wave of
excitation" accompanied by an
electric change lasts for approximately 1 to 2 seconds after the
contraction of the cardiac muscle. The
elect. Answer: set 2
● Which statement is not listed as a detail within the passage?
A. Changes in the ECG are typically used for diagnosis of abnormal
cardiac rhythm.
B. The signal has a characteristic record called the electrocardiogram.
C. The "wave of excitation" starts at the SA node.
D. The "wave of excitation" spreads through the heart wall and is
accompanied by electric
changes.. Answer: A. Changes in the ECG are typically used for
diagnosis of abnormal cardiac rhythm.
● What is the meaning of the word emitting as it is used in the second
paragraph?
