We are finally ready to build and test a prototype! Choose a category 3 hurricane and then the window protection and roofing materials you think will withstand the storm. Remember to always plan to spend as few credits as you can and still keep the home protected. Which combination gives you the best protection for the least cost?

1. plywood + extra nails (2 credits)
2. plywood + steel clips (4 credits)
3. storm panels + extra nails (4 credits)
4. storm panel + tie down (5 credits)

To determine the best combination of window protection and roofing materials that provide the best protection for the least cost during a category 3 hurricane, we will compare the four options:

1. Plywood + Extra Nails (2 credits)
2. Plywood + Steel Clips (4 credits)
3. Storm Panels + Extra Nails (4 credits)
4. Storm Panels + Tie Down (5 credits)

Considering cost-effectiveness, Option 1 (Plywood + Extra Nails) seems to be the most budget-friendly, requiring only 2 credits. However, plywood might not provide the same level of protection as storm panels.

Comparing storm panel options, both Option 3 (Storm Panels + Extra Nails) and Option 4 (Storm Panels + Tie Down) would cost more than plywood solutions. However, storm panels generally offer better protection.

To make the final decision, we should consider the added strength and durability of steel clips (Option 2) and tie-downs (Option 4) compared to using extra nails. While they come at a slightly higher cost, they could provide better resistance against strong winds.

Considering the overall balance between protection and cost, Option 2 (Plywood + Steel Clips) might be the optimal choice. It combines the use of plywood for roofing with steel clips for window protection, providing reliable resistance to hurricane forces with a cost-efficient approach.
