Which of the following describes a wet pipe fire protection system?
1- Equipped with water to supply upon activation of the fire system in the main pipe as well as the branches
2-Pipes are kept constantly wet in order to increase humidity levels within building spaces and reduce the threat of fire
3- Fire system is activated when a gas is released whereby water then flows through the pipes to eliminate fires
4-Pipes are connected directly to the hydrant system on the site and can be manually activated at the hydrant
Most commonly used sprinkler systems are wet pipe systems, which are equip with water to supply upon activation, both in the main pipe as well as the branches. Due to the risk of leakage, one must take precautions when selecting this simple system for certain spaces.

Unlike flashings, _______ is the only component of a wall that can and should be considered sacrificial.
- face mortar - brick - trim - insulation
By specifying face mortar that is softer and less durable than the masonry it binds, we insure that stresses in the wall cause cracking along mortar joints instead of the more costly brick or stone.
Typically 3 courses of brick with mortar will measure ______ inches height.

Which of the following are associated with types of Ownership? Select all that apply
- Fee Simple
- Condominium
- Cooperative
- Leasehold
- Fee Absolute
- Parcel
- Zoning
The following types of Ownership are;
Fee Simple or Fee Absolute - the owner has absolute title or ownership, which he can transfer by sale (for example, private homes).
Condominium - the buyer obtains fee simple ownership for a portion of a structure. Usually, one also owns part of shared communal areas (lobby, community room), which means they also have a shared financial responsibility to maintain those areas.
Cooperative - differs significantly from condominium in that the owner does not legally own a specific portion of the physical property. He/she owns instead a share in a corporation which in turn, owns the land and structures.
Leasehold - is an even more restrictive form of real estate tenancy. The lessee, the person whom the lease is granted, has the right to use a piece of property under certain conditions for a certain time limit. Lessee assumes all rights as an owner (i.e. sublease) and liabilities (i.e. taxes) but has no right to sell the property. In some cases, the lease period is as long as 99 years.
