1. High cost and low fore-resistance are classified as
1. advantage of construction materials
2. disadvantages
2. Cement, brick, and concrete may serve as examples of
1. natural materials
2. artificial materials
3. Durability, strength, and high fire-resistance are properties
1. of stone
2. of wood
1High cost and low fore-resistance are classified as-2disadvantages
2Cement, brick, and concrete may serve as examples of-2artificial materials
3Durability, strength, and high fire-resistance are properties-1of stone
The correct answer would be option 2, disadvantages.
Explanation: High cost and low fire-resistance are characteristics that make a construction material less preferable or advantageous. Therefore, they can be considered as disadvantages.
2. Cement, brick, and concrete may serve as examples of:
The correct answer would be option 2, artificial materials.
Explanation: Cement, brick, and concrete are man-made or artificial materials that are commonly used in construction. They are produced by combining various natural materials such as sand, limestone, and clay, but the final product is considered artificial.
3. Durability, strength, and high fire-resistance are properties:
The correct answer would be option 1, of stone.
Explanation: Durability, strength, and high fire-resistance are qualities that are typically associated with stone as a construction material. Stone has been regarded as one of the most durable and fire-resistant materials throughout history.
To summarize:
1. High cost and low fire-resistance are disadvantages because they make a construction material less favorable.
2. Cement, brick, and concrete are examples of artificial materials.
3. Durability, strength, and high fire-resistance are properties commonly associated with stone as a construction material.
