Clocks made before 1687 had only one hand , the hour hand
-
True
-
False
Early mechanical clocks (before the minute hand was introduced) typically only had an hour hand. The minute hand became more common in clock design during the late 17th and early 18th centuries as clockmaking precision improved.
To answer this question, we need to understand the history of clocks.
Option A) True - This option is correct. Clocks made before 1687 indeed had only one hand, which was the hour hand. These clocks were known as "hour clocks" or "single-handed clocks." They did not have a minute hand or a second hand.
Option B) False - This option is incorrect. As mentioned above, clocks made before 1687 had only one hand, which was the hour hand. Therefore, the statement is true.
The correct answer is A) True. Clocks made before 1687 had only one hand, the hour hand.
