Attempting to repair or fix a computer yourself can be risky and may lead to further damage if you are not knowledgeable or experienced in computer repair. It is often advisable to seek professional help or assistance from someone with expertise in computer repairs to avoid causing more harm.

Explanation
Running or horse-playing in the STEM lab is a bad idea because it can lead to accidents or damage to equipment. The lab is likely to contain delicate and expensive equipment, chemicals, and other materials that could be dangerous if mishandled. Running or engaging in horse-play increases the risk of tripping, knocking over equipment, or causing spills or other accidents that could harm oneself or others. Therefore, it is important to follow safety guidelines and avoid running or horse-playing in the STEM lab.

Explanation
To ensure safety and easy movement in the area, it is important to keep isles and walkways clear of obstructions and personal objects. Chairs, rugs, and tables can also obstruct the path, but book bags specifically pose a potential hazard as they can easily be tripped over or cause someone to lose balance. Therefore, it is necessary to keep book bags out of the way to maintain a clear and safe passage.

Explanation
To ensure that any progress made on a file or project is not lost in the event of a power failure, it is important to periodically save the work. Saving the file or project allows for the data to be stored and accessed later, even if there is an unexpected interruption in power. By regularly saving, any recent changes or updates can be preserved and easily recovered if necessary.

Explanation
The tip of a hot glue gun is the part that gets extremely hot and is used to dispense the glue. It is important to never touch the tip of the hot glue gun because it can cause severe burns or injuries.

Explanation
The correct answer is cables. This is because loose cables can be a tripping hazard when walking or moving chairs. They can easily get tangled around your feet or cause you to lose balance, leading to accidents or injuries.

Explanation
The statement advises not to connect any "outside objects" to the computer without permission. This implies that any external devices or items that are not meant to be connected to the computer should not be plugged in without proper authorization. The use of keyboards, headphones, and mice are typically allowed and expected, so they are not included in the warning.

Explanation
Maintaining good posture while working at a computer is important for several reasons. It helps to prevent strain and injury to the neck, back, and shoulders, as well as reducing the risk of developing musculoskeletal disorders. Good posture also promotes proper alignment of the spine, allowing for better circulation and improved breathing. It can also enhance concentration and productivity by reducing fatigue and discomfort. Therefore, it is crucial to sit up straight and maintain good posture while working at a computer.

Explanation
Taking regular breaks from staring at a computer screen is important to prevent eye strain and fatigue. Glancing away from the screen allows the eyes to rest and refocus on objects at different distances, reducing the risk of developing computer vision syndrome. This practice also helps to maintain productivity and concentration by preventing mental fatigue. Therefore, periodically glancing away from the computer screen is a recommended habit when working on a long document or project.

Explanation
It is important to keep food and drinks away from computers and electrical equipment to prevent any accidental spills or damage caused by liquid or food particles. Liquids can cause short circuits and damage the internal components of the equipment, while food particles can attract pests and cause clogging or overheating of the devices. Therefore, it is advised to maintain a clean and safe environment by keeping food and drinks away from computers and electrical equipment.

Explanation
When cutting with scissors or snips, it is important to exercise caution. This means being careful and paying attention to avoid any accidents or injuries. Caution is necessary because scissors and snips have sharp blades that can cause harm if not handled properly. It is essential to use caution to ensure personal safety and prevent any accidents while cutting.

Explanation
When you have a cold, it is important to wash your hands before and after using the computer to prevent the spread of germs. Hands are the part of the body that comes into contact with various surfaces, including the computer keyboard and mouse, which can harbor germs. Washing your hands helps to remove any viruses or bacteria that may be present, reducing the risk of spreading the cold to others or reinfecting yourself.
