89.Salt deposits and moisture threaten to destroy the
Mohenjo-Daro excavation in Pakistan, the site of an
ancient civilization that flourished at the same time
as the civilizations in the Nile Delta and the river
valleys of the Tigris and Euphrates.
The explanation in OG says flourished uses the simple past tense.
My confusion: since "flourished" is a past tense, then threaten appearing in the same sentence should be "threatened", too.
Correct me!
