Chemical reactions in the material used to make matches, and the cardboard... so hope this helps :)
NOTE: im not to good at this stuff so i rlllllly hope it helps
Hi;
In the question, Robert gives the explanation that there is an error in the BIOS. A BIOS (Standing for Basic Input & Output System) is a ROM chip, and is vital for the computer to initialize devices such as RAM, the CPU, etc. If there is ever an error there, a computer simply cannot boot.
From the options given, your answer given would be C. ROM.
I hope this helps!
Drones are become more advanced than ever before. Are now, they are starting to impact recreation. They are small, light, and can maneuver incredibly fast. They are being used in movies, skits, short films, and even high-end videos. Here are some ways drones are changing entertainment:
- Providing high-quality filming, even from 200 feet in the air.
- Reaching spaces where bulky helicopters cannot fit into safely
- Laser shows, where drones shine lights and lasers.
Right now, if you tried to hold your phone still to capture a video, you would not be able to do it. Upon checking the footage, you would see the camera shaking, even if it's just tiny bit. While you can lean it on a surface to fix this, it simply cannot be done in the air to capture. Not to worry, though, you've got drones. They can shoot a steady shot 200 feet in the air. The only thing that could rival drones are expensive, bulky choppers. The drones are cheaper and are mass produced.
However, drones are not only being used to filming movies and films. They are also being used for a different kind of entertainment: Shows. Drones move in formation and shine lights in the night sky, like we saw in the Winter Olympics. They are truly stunning(pics attached).
Answer:
The correct option is Option C: It matches a new problem with a previously solved problem and its solution.
Explanation:
Case-based reasoning (CBR) is used when someone tries to solve new problems based on old problems that were similar. The person applying case-based reasoning would look for the solutions to these similar past problems and try to apply them to the new case. For example, a doctor who tries to treat a patient based on what was successful with a prior patient with a similar problem is applying case-based reasoning. In some instances, these problems are available in a database and ideally, that is how it is conceived, but it would depend on the field and the kind of problems. There is no universal global network dedicated to CBR as a whole (other than generic searches on the internet in general). One example of a specific CBR database is the European Nuclear Preparedness system called PREPARE.
