The correct answers are A. conventional and D. iconoclastic.

Explanation
- Logic: The sentence relies on a clear contrast signaled by the pivot word "yet." The documentary's opening frames promise a "thoroughgoing reassessment of the general's culpability"-meaning it promises a radical, rule-breaking, or tradition-shattering perspective. However ("yet"), the narrative that actually unfolds is the opposite of this promise.
- Blank (i): Because the film fails to deliver a radical reassessment and instead defers to the "official record," its judgments are A. conventional (following traditional or accepted standards). Tendentious means biased or promoting a controversial viewpoint, which contradicts its safe reliance on the official record. Disjointed means lacking coherence, which is unrelated to the nature of its judgments.
- Blank (ii): The colon introduces a breakdown of this conventional nature: the film is highly deferential to the official record rather than being genuinely D. iconoclastic (attacking cherished beliefs or traditional institutions). This perfectly echoes the "thoroughgoing reassessment" promised at the start but ultimately undelivered. Polemical means a harsh verbal attack, but it lacks the specific context of breaking away from established historical consensus/orthodoxy. Analytical is too neutral to match the missing contrast with "deferential."

Difficulty Level
Medium-High. This question hinges on understanding structural irony (promising a radical change but delivering standard conventions) and recognizing the precise vocabulary pairing between conventional and iconoclastic.
