Why it is not presentable

  • Quoted a figure the analysis says not to quote
  • Did not give the analysis's recommendation within the first two slides
  • Drew a conclusion from a figure without its caveat

In detail

  • Slide 4 quotes 6,300: the unverified 6,300-signature petition.
  • Caveat missing: respondents were mostly weekly users (82%, against 21% of card holders), not representative of residents.
  1. Slide 1 of Gemini 3.5 Flash Lite's deck
    Slide 1Polished The subtitle has low contrast against the purple background, making the central savings message too faint for reliable public-meeting projection.
  2. Slide 2 of Gemini 3.5 Flash Lite's deck
    Slide 2Acceptable The title names a topic rather than stating the decision required.Topic-label title ('The Decision & Context') rather than a takeaway title
  3. Slide 3 of Gemini 3.5 Flash Lite's deck
    Slide 3Acceptable The main conclusion is buried in a three-line takeaway paragraph rather than expressed in the title.Topic-label title; the takeaway (Option B meets the target with the least opposition) is buried in a paragraph at the bottom
  4. Slide 4 of Gemini 3.5 Flash Lite's deck
    Slide 4Acceptable The topic title does not communicate the principal takeaway.Topic-label title with no stated takeaway
  5. Slide 5 of Gemini 3.5 Flash Lite's deck
    Slide 5Acceptable The three options have identical visual treatment, with no emphasis on the overall assessment or preferred option.Content fills only the top ~40% of the three tall cards, leaving large empty space below
  6. Slide 6 of Gemini 3.5 Flash Lite's deck
    Slide 6Acceptable The recommendation is clear, but its supporting points remain long prose bullets rather than visually distinct commitments.Generic 'Recommendation' title; 'Adopt Option B' could itself be the title
