1.
To have structural strength and stability a building needs a good ______.
Correct Answer
B. Foundation
Explanation
A building needs a good foundation in order to have structural strength and stability. The foundation is the base of the building that supports the entire structure and transfers the weight of the building to the ground. It provides stability and prevents the building from sinking or shifting. A strong foundation is essential to ensure that the building can withstand various forces, such as wind, earthquakes, and the weight of the structure itself. Without a solid foundation, the building would be at risk of collapsing or experiencing structural damage.
2.
Plain clay tiles are similar to slates in covering capacity although their size is normally larger than that of slates.
Correct Answer
B. False
Explanation
The statement is false because plain clay tiles are not similar to slates in covering capacity. While their size may be larger, they do not have the same covering capacity as slates.
3.
The ______ is the name which is given to the angle which lies between intersecting roofs.
Correct Answer
D. Valley
Explanation
A valley is the name given to the angle which lies between intersecting roofs. It is formed when two sloping roofs meet at a downward angle, creating a V-shaped indentation. The valley is an important architectural feature as it helps to channel rainwater and snowmelt off the roof and into the gutters, preventing water damage and leakage.
4.
A ______ board is fixed at the end of the rafters in order to provide a support for the rain water gutter.
Correct Answer
A. Fascia
Explanation
A fascia board is fixed at the end of the rafters to provide support for the rainwater gutter. The fascia board is typically a long, straight board that runs horizontally along the lower edge of the roof. It is attached to the ends of the rafters and serves as a base for attaching the gutter system. The fascia board helps to protect the roof and the underlying structure from water damage by directing rainwater into the gutter and away from the building.
5.
External maintenance of any building should include a yearly inspection, a record of which should be kept.
Correct Answer
A. True
Explanation
External maintenance of any building should include a yearly inspection to ensure that any potential issues or damages are identified and addressed in a timely manner. Keeping a record of these inspections is important for documentation purposes and to track the maintenance history of the building. This helps in maintaining the overall condition and safety of the building, as well as complying with any legal or regulatory requirements. Therefore, the statement is true.
6.
Windows are an economical and convenient form of ventilation and they should form ______ of the floor space.
Correct Answer
D. One tenth
Explanation
Windows are an economical and convenient form of ventilation, but they should not occupy too much of the floor space. Therefore, it is recommended that windows should only occupy a small portion of the floor space. The answer "one tenth" suggests that windows should occupy approximately 10% of the floor space, allowing for sufficient ventilation while still leaving ample room for other purposes.
7.
Internal walls, external walls, roof, floors and stairs form the primary elements of the superstructure of a building.
Correct Answer
A. True
Explanation
The statement is true because the internal walls, external walls, roof, floors, and stairs are indeed the primary elements that make up the superstructure of a building. The internal walls divide the space within the building, the external walls provide structural support and protection from the elements, the roof covers and protects the building, the floors provide the levels and support for the occupants, and the stairs provide access between the different levels of the building. These elements are essential for the overall structure and functionality of a building.
8.
The continuous ______ are raised and padded in a range of different coloured plastics and designs.
Correct Answer
D. Quilting and quilted panels
Explanation
The correct answer is "quilting and quilted panels." This answer makes sense in the context of the sentence as it describes a continuous material that is raised and padded. Quilting and quilted panels are commonly used in various applications, such as upholstery, clothing, and interior design, where they provide texture, comfort, and visual interest. The other options, such as ceiling tiles, room separators, and ribbon wirework, do not fit the description of being raised and padded in the same way quilting and quilted panels do.
9.
______ are the measure of current flow.
Correct Answer
C. Amperes
Explanation
Amperes are the measure of current flow. Current is the flow of electric charge in a circuit, and it is measured in amperes. Voltage, wattage, and ohms are related to current but do not directly measure the flow of current. Voltage is the potential difference that drives the current flow, wattage is the rate at which electrical energy is consumed or produced, and ohms is the unit of electrical resistance. Therefore, the correct answer is amperes.
10.
Safety devices in connection with electricity include adequate insulation, properly rated fuses or circuit breakers, and earthing.
Correct Answer
A. True
Explanation
Safety devices in connection with electricity, such as adequate insulation, properly rated fuses or circuit breakers, and earthing, are necessary to prevent electrical accidents and ensure the safety of individuals and property. These devices help to protect against electrical shocks, short circuits, and overloads. Therefore, the statement that safety devices in connection with electricity include adequate insulation, properly rated fuses or circuit breakers, and earthing is true.
11.
There are two hot water circulating systems, the direct and the indirect.
Correct Answer
A. True
Explanation
The statement is true because there are indeed two hot water circulating systems: the direct and the indirect. The direct system circulates hot water directly from the water heater to the taps or fixtures, providing instant hot water. The indirect system, on the other hand, uses a separate loop and a heat exchanger to transfer heat from the water heater to the taps, ensuring that the water in the taps does not mix with the water in the heating system.
12.
_______ is the passing of heat energy by the relative movement of the heated particles within a liquid or a gas.
Correct Answer
B. Convection
Explanation
Convection is the correct answer because it refers to the transfer of heat energy through the movement of heated particles within a liquid or a gas. In convection, the heated particles become less dense and rise, while the cooler particles sink, creating a circular motion that transfers heat. This process is commonly observed in everyday life, such as when hot air rises and cold air sinks, causing wind currents or when boiling water forms bubbles that rise to the surface.
13.
Most boilers cannot be adapted to produce hot water or steam.
Correct Answer
B. False
Explanation
Most boilers can be adapted to produce hot water or steam. This means that they have the capability to be modified or adjusted in order to generate either hot water or steam, depending on the specific needs or requirements. Therefore, the statement that most boilers cannot be adapted to produce hot water or steam is false.
