Question Easy
The line graph shows the number of near-Earth asteroids discovered by the Spacewatch survey from 2003 to 2010.
During which period was the increase in the number of near-Earth asteroids discovered the greatest?
A) From 2003 to 2004
B) From 2004 to 2005
C) From 2005 to 2006
D) From 2007 to 2008
▶️Answer/Explanation
Ans:D
We will compare the increase in the number of near-Earth asteroids discovered from year to year by examining the vertical distances between points on the graph.
1. From 2003 to 2004:
In 2003, the number of asteroids discovered is approximately 50.8.
In 2004, the number of asteroids discovered is approximately 70.2.
Increase: \( 70.2 – 50.8 = 19.4 \).
2. From 2004 to 2005:
In 2004, the number of asteroids discovered is approximately 70.2.
In 2005, the number of asteroids discovered is approximately 80.3.
Increase: \( 80.3 – 70.2 = 10.1 \).
3. From 2005 to 2006:
In 2005, the number of asteroids discovered is approximately 80.3.
In 2006, the number of asteroids discovered is approximately 90.9.
Increase: \( 90.9 – 80.3 = 10.6 \).
4. From 2007 to 2008:
In 2007, the number of asteroids discovered is approximately 40.8.
In 2008, the number of asteroids discovered is approximately 80.4.
Increase: \( 80.4 – 40.8 = 39.6 \).
By comparing these increases, we see that the greatest increase occurred from 2007 to 2008.
