To avoid slipping is correct because wet surfaces reduce friction, which can cause accidents and falls in a work area.

Polyester or nylon is correct because these synthetic fabrics melt easily and catch fire instantly, making them dangerous near heat.

Foam soaked in clean water is correct because using saliva to turn pages is unhygienic and can spread harmful germs.

Supervision of teacher is correct because adult guidance ensures that students follow safety rules and avoid accidents.

Apron is correct because it protects your clothes and skin from accidental chemical spills and stains.

Near the entrance is correct because safety tools must be easily accessible to everyone during an emergency evacuation.

Do not try to use it is correct because unlabeled chemicals can be highly toxic or reactive, posing a severe safety hazard.

The lab attendant is correct because they are trained to handle emergencies, first aid, and chemical spills safely.

Model making is correct because building physical structures improves hand-eye coordination and technical understanding.

Skewer is correct because these thin rods are commonly used as support beams in school model-making activities.

All of the above is correct because skewers, ice cream sticks, thread, paper, and glue are all needed to assemble the bridge model.

Spirit level is correct because this tool uses a fluid-filled tube with an air bubble to indicate if a surface is flat and level.

Coloured spirit is correct because alcohol (spirit) remains liquid at low temperatures and the color makes the bubble easy to see.

The bubble is exactly in the middle is correct because the marked lines on the tube show that the level is perfectly balanced on both sides.

Three is correct because having three tubes allows the tool to check horizontal, vertical, and 45-degree angle surfaces.

Both (A) and (B) is correct because the multiple tubes are set at different angles to measure both upright walls and slanted slopes.

Plumb line is correct because this simple tool uses gravity to create a perfect vertical reference line for builders.

Plumb bob is correct because this heavy weight pulls the string straight down, creating an accurate vertical line.

The hanging bob just touches the pole is correct because this contact proves that the pole is perfectly aligned with the vertical string.

Tiny light emitting bulbs is correct because LEDs are semiconductor devices that produce light efficiently when current passes through them.

2 to 3 Volts is correct because LEDs operate on very low power, making them safe and energy-efficient for small projects.

It is the longer leg is correct because manufacturers design the positive lead of the LED to be physically longer than the negative lead.

It is the shorter leg is correct because the negative lead (cathode) of an LED is made shorter to help users connect it correctly to a circuit.

12 V battery is correct because the combined voltage requirement of the connected LED sets matches this specific battery output.

It can burn the LEDs instantly is correct because high A.C. voltage will destroy the low-voltage bulbs and cause a dangerous short circuit.

Innovation is correct because creating advanced tools like automatic washing machines or electric cars represents technological progress.

Positive attitude is correct because staying hopeful in difficult times helps entrepreneurs find creative solutions to grow.

Guitar is correct because stretching rubber bands over a hollow box allows them to vibrate and produce musical tones when plucked.

First aid is correct because it is the immediate, life-saving assistance provided to a patient before professional medical help arrives.

Drop, Cover, Hold on is correct as dropping down, getting under a sturdy desk, and holding on protects you from falling debris.

Rescue 1122 unit is correct because they are the official emergency response team trained to teach students about disaster drills and first aid.

Stop what you are doing is correct because immediate attention and calm action are necessary to safely evacuate the building during a fire.

Fire extinguisher is correct because it contains pressurized chemicals designed to put out small fires quickly before they spread.
