Below 7 (<70%) Review Dossier A3 & B4
1 Correct: A. Southern Arizona
Dossier Context
Reading Evidence: Solton is a desert community located in Southern Arizona facing extreme heat, requiring year-round cooling.
2 Correct: C. More than 300
Section A3 Context
Reading Evidence: Solton experiences over 300 hot days per year. Section A3 emphasizes that buildings must run air conditioning year-round.
3 Correct: A. Futura
Section B4 Header
Reading Evidence: Chapter 2 states: "Futura Engineering's Work on Rooftops" and "Futura will submit a proposal for building modifications that focuses on the roofs of Solton."
4 Correct: A. Combustion (burning) of fuels
Section A3 (Criterion 1)
Reading Evidence: Section A3 states: "most of the electricity we use is generated through combustion (burning) of fuels at power plants."
5 Correct: C. Carbon dioxide
Sections A3 & B4
Reading Evidence: Both texts explain that combustion releases carbon dioxide (CO2), which builds up in the atmosphere and increases Earth's temperature.

Solton Rooftops Answer Key (Questions 6–10 Continued)
Explanations & Evidence
6 Correct: B. The changes are easy to see from street level
Section A3 (Criterion 2)
Reading Evidence: The text explains that "changing the roofs can affect the historic value... especially when the buildings have pitched (slanted) roofs so that the changes are easy to see from street level."
7 Correct: B. Must not include any major structural changes
Section A3 (Constraints)
Reading Evidence: A key constraint specifies: "The proposed design must not include any major structural changes to the buildings, such as changes in the shape or direction of the roof."
8 Correct: B. White roofs and solar roofs
Sections A3 & B4
Reading Evidence: Section A3 states: "The roof modifications include only white roofs and solar roofs." Section B4 confirms Futura evaluated these two options.
9 Correct: C. About half
Section B4 (Paragraph 1)
Reading Evidence: Section B4 explicitly notes: "about half of home energy use goes toward indoor temperature control" in the United States.
10 Correct: C. By more than 20%
Section B4 (Paragraph 2)
Reading Evidence: Section B4 states: "By changing roofs, U.S. communities can lower their energy use by more than 20% and significantly reduce their climate impact."
Engineering Concept Review: Criteria vs. Constraints
Criteria (Goals to Optimize)
- Reduce climate impact (cut electricity & CO2)
- Preserve historic building value
- Keep project costs low
Constraints (Non-Negotiable Limits)
- No major structural changes (no shape/pitch changes)
- Do not cut down any trees
- Only use white roofs and solar roofs
