A standard rain gauge consists of a funnel-shaped collector attached to a long measuring tube. The cross-sectional area of the collector is ____ times that of the tube. Hence, rain falling into the collector is amplified ____ in the tube, permitting measurements of great precision.
A)2; twofold
B)4; fourfold
C)6; sixfold
D)8; eightfold
E)10; tenfold

The cross-sectional area of the collector in a standard rain gauge is typically 10 times that of the tube. This design amplifies the volume of rain collected by the funnel into the tube tenfold, allowing for more precise measurements of small amounts of rainfall.
