English Conditional Sentences
Choose the sentence with no conditional error.
Explanation
This describes a hypothetical, large-scale scenario rather than a real plan, so it correctly follows the second conditional pattern: past simple in the if-clause, "would" in the main clause.

Hint
Hypothetical scenarios about what governments or society "would" do (not actual plans) usually call for second conditional, not first.
