Q: Read the following article and answer the question. Article: The physical memory dump error is a big problem that affects even the most advanced computer systems.Although it's quite a rare error, it's one of the most stopping what you're doing and restarting your computer--making you lose all your unsaved data.This is a big problem, but there is actually a very easy way to fix it. There are two reasons why the physical memory dump happens.The first is pretty simple and is to do with the "hardware", and if any of these pieces are not fit for your system, it will cause the physical memory dump.So, if you've recently added any hardware to your PC, then take that out and see if it works. The other reason is your system, the "registry".The registry is a big database that operates in the background of Windows, storing all sorts of settings and information about your PC.The problem with the registry is that since it has so many important files inside, it's constantly got hundreds of files open every time you use your PC.And because there are so many files to open at once, Windows is constantly getting confused, leading it to save many of these files in the wrong way.These files go wrong when saved wrongly, making them difficult for your computer to read.However, if it can't read the files at all, it has no choice but to stop everything it's doing and restart your PC.This is why the physical memory dump error appears so easily--because when a registry file is so wrong that it can't be read, your computer needs to refresh itself immediately. This latter reason for causing the physical memory dump is actually extremely common and the likelihood is that your PC is suffering from it, if you're seeing this error.Luckily, it's also incredibly easy to fix--you just need to use a software tool called a "registry cleaner" to go through the registry and fix all the problems in there. Question: What does a registry cleaner means? Answer: | OPTIONS:
- A software which can help you save time.
- A software which can remove unnecessary files
- A software which can repair the machine.
- a software which makes your PC down.
A: A software which can remove unnecessary files

Q: Read the following article and answer the question. Article: I was 230 pounds this spring and I decided to get down to a healthier 200.In a house full of food,including snacks bought for my 7yearold sons,I had a hard time cutting calories. Then I noticed my neighbors were having diet meals .I decided to do the same,knowing I would never be able to stick to a diet if I had to do the buying and cooking myself. I was looking for food that I could afford but I might take a diet more seriously if it hurt me in the wallet. After online searches,I decided to compare the offerings of four companies:Zone Manhattan,Chefs Diet,NuKitchen and eDiets. All four would send the meals to my door. Three send food daily,while eDiets sends a large package once a week. There were dozens of companies I could have chosen.Research suggests that the economic crisis has made diet programs less _ .Consumers prefer doityourself diets with foods bought from the supermarket. NuKitchen regards itself as the "personal chef".I ordered the fiveday plan ($230.53) and the taste was disappointing. I neither lost nor gained weight on the food. eDiets promises "healthy,delicious meals sent to your door".I ordered five breakfasts,five lunches and five dinners. My total cost was $119.70,or less than $25 a day. Overall,the food from eDiets was better than that from NuKitchen. Chefs Diet charged $380.99 for seven days,making it the most expensive of the four services.I never tasted anything terrible,but I never tasted anything that made me want to renew for a second week. Zone Manhattan charged $349.80,with tax,for a week's supply of food,or about $50 a day.I liked the food so much that I lost six pounds in the first four days on the diet. Question: We can learn from the passage that _ . Answer: | OPTIONS:
- the author gained weight on the food from Nukitchen
- the author would choose the food of Zone Manhattan
- the food from eDiets was the worst of the four
- Zone Manhattan sends food once a week
