ANSWERS 
A CHRONICLE OF TIMEKEEPING 
QUESTIONS 1-4: READING PASSAGE HAS EIGHT 
PARAGRAPHS, 
A-H

1. A DESCRIPTION OF AN EARLY TIMEKEEPING INVENTION 
AFFECTED BY COLD TEMPERATURES. 
Keywords:early, timekeeping, cold temperatures 
In paragraph D, the writer indicates that “In order to track temporal hours during 
the day, inventors 
created sundials, which indicate time by the length or direction of the sun‟s shadow. The sun
dial‟s counterpart, the water clock, was designed to measure temporal hours at night. One of the first 
water clocks was a basin […]. Although these devices performed satisfactorily around the 
Mediterranean; they could not always be depended on in the cloudy and freezing weather of northern 
Europe.” 
– early~one of the first 
– cold=freezing 
=>ANSWER: D 
2. AN 
EXPLANATION OF THE IMPORTANCE OF GEOGRAPHY IN THE
DEVELOPMENT OF THE CALENDAR IN FARMING 
COMMUNITIES. 
Keywords: geography, calendar, farming communities 
In paragraph B, the writer states that “Before the invention of artificial light, the moon had gr
eater 
social impact. And, for those living near the equator in particular, its waxing and waning was 
more 
conspicuous than the passing of the seasons. Hence, the calendars that were developed at the l
ower 
latitudes were influenced more by the lunar cycle than by the solar year. In more northern c
limes, however, where seasonal agriculture was practised, the solar year became more crucial.” 
– farming=agriculture 
=>ANSWER: B 
3. A DESCRIPTION OF THE ORIGINS OF THE PENDULUM CLOCK 
Keywords: origins, pendulum clock 
In paragraph F, the writer says that “By the 16th century, a pendulum clock had been devised, but the 


143 
pendulum swung in a large arc and thus was not very efficient.” 
=>ANSWER: F 
4. DETAILS OF THE SIMULTANEOUS EFFORTS OF DIFFERENT 
SOCIETIES TO CALCULATE TIME USING UNIFORM HOURS. 
Keywords: calculate time, uniform hours 
paragraph E, the writer says that “….in the early 14 century, a number of systems evolved. The 
schemes that divided the day into 24 equal parts varied according to the start of the count: Italian hours 
began at sunset, Babylonian hours at sunrise, astronomical hours at midday and „great clock‟ hours, 
used for some large public clocks in Germany, at midnight. Eventually these were superseded by 
„small clock‟, or French, hours, which split the day into two 12-hour periods commencing at 
midnight.” So, these efforts all occurred at around the same time (= simultaneously) in the early 
14th century, based on 24 equal parts (= uniform hours) in different countries (= different societies). 
=>ANSWER: E 
QUESTIONS 5-8: LOOK AT THE FOLLOWING EVENTS 
(QUESTIONS 
5-8
) AND THE LIST OF NATIONALITIES BELOW. 
5. THEY DEVISED A CIVIL CALENDAR IN WHICH THE MONTHS WERE 
EQUAL IN LENGTH. 
Keywords: a civil calendar, months, equal in length 
In paragraph C, the writer explains that “Centuries before the Roman Empire, the Egyptians h
ad formulated a municipal calendar having 12 months of 30 days, with five days added to approximate 
the solar year.” Therefore, the Egyptians devised this calendar. 
– devised=formulated 
– civil=municipal 
– he months were equal in length ~ 12 months of 30 days 
=>ANSWER: B 
6. THEY DIVIDED THE DAY INTO TWO EQUAL HALVES 
Keywords: divided, two equal halves 
In paragraph E, the writer indicates that “Eventually, these were superseded by „small clock‟,
or French, hours, which split the day into two 12-hour periods commencing at midnight.” 
– divided=split 
– two equal halves ~ two 12-hour periods 
=>ANSWER: F 
7. THEY DEVELOPED A NEW CABINET SHAPE FOR A TYPE OF 
TIMEKEEPER. 
Keywords: new, cabinet shape, timekeeper. 
In paragraph G, the writer says that in England in 1670, the invention of the anchor escapem
ent enabled the pendulum to travel in a very small arc, which means that it moved only a short 
distance. So a long pendulum which beat once every second could be used “….and thus led to the 
development of a new floor-standing case design, which became known as the grandfather 
clock.‟ So, this grandfather clock, a type of timekeeper, stood on the floor, and the pendulum moved 
inside the tall case, shaped lack a cabinet. 
=>ANSWER: D 


144 
8. THEY CREATED A CALENDAR TO ORGANIZE PUBLIC EVENTS AND 
WORK SCHEDULES. 
Keywords: calendar, organize public events, work schedules

=>ANSWER: A 
QUESTIONS 9-13: LABEL THE DIAGRAM BELOW. 
9-13. HOW THE 1670 LEVER-BASED DEVICE WORKED 
Keywords: 1670, lever-based device. Thus, all the answers will be found in paragraph G. 
9. ESCAPEMENT (RESEMBLING…..) 
In paragraph G, the writer says that “It was called the anchor escapement, which was a lever-based 
device shaped like a ship‟s anchor” 
– resembling=be shaped like 
=>ANSWER: (ship‟s) anchor 
10. THE….. 
11.THE…… 
In paragraph G, the writer explains that “The motion of a pendulum rocks this device (escapement) so

12-13. A 12…..WHICH BEATS EACH 13….. 
In paragraph G, the writer says that “Moreover, this invention allowed the use of a long
