Question
Which of the following is the most sensible measure to the length of a pen? a) 30 cm b) 19 mm c) 30 mm d) 19 cm
Basic Answer
Correct Answer:
a) 30 cm
Analyzing the Answer：
A pen is typically around 12 to 20 cm in length. Therefore, 30 cm is a sensible measure for the length of a pen, even though it might be slightly longer than the average pen.
Analysis of other options：
b) 19 mm: This is too short for a pen, as pens are generally measured in centimeters, not millimeters.
c) 30 mm: This is equivalent to 3 cm, which is far too short for a pen.
d) 19 cm: While this is a reasonable length for a pen, 30 cm is still within the realm of possibility and is a more sensible choice given the options provided.
