Adversities means difficulties or hardships. The 'despite' indicates a contrast with remaining optimistic.
Diligence means careful and persistent effort. It fits perfectly with 'completing the project ahead of schedule'.
Authoritarian (antonym of democratic/transparent) fits the contrast. The regime suppressed freedom, contrasting with the new government's promise of freedom and transparency.
Garrulous, loquacious, and voluble all mean talkative or verbose—antonyms of taciturn. Cryptic means mysterious or unclear, which is unrelated to taciturnity.
Concise is the antonym of verbose (wordy). The contrast indicated by 'while' requires an opposite quality. Concise means brief and to the point.

Perspicacious (keen insight) correctly pairs with market analysis; no error exists.
Ephemeral means short-lived; permanent means lasting indefinitely, providing the direct contrast.
Candid means frank and open; evasive means avoiding direct answers, making it the opposite.
Acrimonious means bitter and harsh; harmonious means peaceful and agreeable, making it the direct antonym.
