Explanation:

1. Masonry veneer is secured to structural frames with noncorroding metal anchors to hold it in place while allowing for movement.
2. Fire-resistance ratings require structural members to maintain load-bearing capacity alongside withstanding fire.
3. Firewalls are full-height, 2-4 hour fire-rated assemblies with protected openings, running from foundation to roof.
4. Type X gypsum board has vermiculite in its core to prevent shrinkage during fire calcination.
5. Firestopping materials seal penetrations in fire-rated assemblies to preserve fire resistance and block smoke.
6. A reinforced concrete column needs a minimum 2-inch cover thickness for a 2-hour fire-resistance rating.
7. Shafts (vertical building openings) are constructed as fire-resistance-rated enclosures, classified as fire barriers to contain fire spread.

Answer:

1. a. noncorroding metal anchors
2. b. provide load-bearing support for the building
3. d. Firewalls
4. c. vermiculite
5. b. Firestopping materials
6. b. 2"
7. b. Fire barriers
