Question

look at the statements below about the 1930s.
loss of grasses left topsoil loose and unprotected.
↓
high winds frequently blew on the great plains.
↓
valuable topsoil needed by farmers was thus blown away.
↓

which statement belongs on the blank line?
○ on farms, crops were not rotated, and soil nutrients were used up.
○ farm production harmed fertile land.
○ millions of acres of productive farmland became barren desert.
○ on ranches, herds overgrazed and damaged grasses.

Explanation:

The sequence describes the chain of events leading to the Dust Bowl in the 1930s. The final step before the blank is topsoil being blown away; the next logical outcome is the transformation of farmland into barren desert. The other options are either earlier causes or too general, not the direct result of lost topsoil.

Answer:

Millions of acres of productive farmland became barren desert.
