Question

read the passage.
finding bombs in germany
during world war ii, american and british forces dropped millions of tons of bombs on german cities. nearly ten percent of the bombs never exploded. the war ended in 1945, but more than two thousand tons of unexploded bombs are still found in germany each year. before any construction project is undertaken, the site must be checked for unexploded bombs. buried bombs are often discovered. for this reason, germany has a special force of firefighters and police officers, called the kwsb, to defuse and remove these bombs. even though the war has been over for seven decades, the kwsb is one of the busiest bomb squads on the planet.
what is the main, or central, idea of the passage?
because there are so many unexploded bombs in germany, the country has a special force trained to defuse them.
almost ten percent of the bombs dropped on germany during world war ii never exploded.
because there is so much construction in germany, the country has a special force trained to defuse bombs.

Explanation:

To determine the main idea, we analyze each option:

• The first option: The passage states that many unexploded bombs remain in Germany (from WWII, with thousands found yearly), and because of this, Germany has the KMBD to defuse them. This matches the overall content.
• The second option: This is a detail about the percentage of unexploded bombs, not the main idea.
• The third option: The passage doesn't emphasize construction as the reason for the special force; it's the presence of unexploded bombs. So this is incorrect.

Answer:

A. Because there are so many unexploded bombs in Germany, the country has a special force trained to defuse them.
