NCAE Technical-Vocational Aptitude 2 — Questions and Answers
Question 1: Which type of fire extinguisher is appropriate for electrical fires?
- Water-based (Class A)
- Foam-based (Class B)
- CO2 or dry chemical (Class C) (Correct answer)
- Wet chemical (Class K)
Correct answer: CO2 or dry chemical (Class C)
Class C fire extinguishers (CO2 or dry chemical) are designed for electrical fires. Water-based extinguishers should never be used on electrical fires as water conducts electricity and can cause electrocution.
Question 2: What does the acronym 'CAD' stand for in technical design?
- Computer-Aided Design (Correct answer)
- Computer and Data
- Creative Art Design
- Calculated Architectural Drawing
Correct answer: Computer-Aided Design
CAD stands for Computer-Aided Design. It refers to the use of computer software to create, modify, analyze, and optimize designs. CAD is widely used in architecture, engineering, and manufacturing.
Question 3: In cooking, what does 'sauteing' mean?
- Cooking food in a large amount of oil
- Cooking food quickly in a small amount of fat over high heat (Correct answer)
- Cooking food slowly in a covered pot
- Cooking food in steam
Correct answer: Cooking food quickly in a small amount of fat over high heat
Sauteing is a cooking method that uses a small amount of fat (oil or butter) in a pan over relatively high heat. The food is cooked quickly and kept moving in the pan to ensure even cooking.
Question 4: Which of the following is a characteristic of a series circuit?
- Multiple paths for current to flow
- The total resistance decreases as more resistors are added
- The current is the same through all components (Correct answer)
- Each component has its own separate path
Correct answer: The current is the same through all components
In a series circuit, there is only one path for current to flow, so the same current passes through all components. If one component fails, the entire circuit is broken.
Question 5: What is the correct unit of measurement for electrical resistance?
- Ampere
- Volt
- Watt
- Ohm (Correct answer)
Correct answer: Ohm
Electrical resistance is measured in ohms (Ω), named after German physicist Georg Simon Ohm. Amperes measure current, volts measure voltage, and watts measure power.
Question 6: In dressmaking, what is a 'pattern' used for?
- To decorate the finished garment
- To serve as a template for cutting fabric pieces (Correct answer)
- To determine the color of the fabric
- To price the finished product
Correct answer: To serve as a template for cutting fabric pieces
In dressmaking, a pattern is a template made from paper or cardboard that is used to cut fabric pieces accurately. It ensures that the garment pieces are the correct size and shape before sewing.
