Question

Which correctly combines the clauses to avoid faulty coordination? More than 1,400 ME 262 turbojets were produced. Fewer than 300 saw combat.

Answer 1

'but'

This coordinating conjunction is the correct addition to the sentence in order to combine the two clauses. The first part of the sentence shows a huge number produces, but the second part shows that only some of them were used. The sentence should read: 

More than 1,400 ME 262 turbojets were produced, but fewer than 300 saw combat.

Answer 2

The correct answer for Gradpoint is"Although more than 1,400 ME 262 turbojets were produced, fewer than 300 saw combat"!!!!
