5つの下線部の正しい訳を教えて欲しです。 至急お願いします🚨🙇

Unit 12 Change the World Basic A few years ago, an obesity* researcher at the University of Washington-named Adam Drewnowski ventured into the supermarket to solve a mystery. He wanted to (1) figure out why (2)poor people were more likely to suffer from obesity in America. Obesity is, as you know, mainly caused by taking in too many calories. For most of history the poor have typically suffered from a shortage of calories, not an excess. So why do the people with the least amount of money to spend on food tend to be overweight today? 目 Drewnowski gave himself a dollar to spend, using it to purchase as many calories as he possibly could. He discovered that he could buy the most calories per dollar in the middle aisles of the supermarket, among the towering piles of* processed food and soft drinks. 3 Processed food is, in the broadest sense, any food that is changed from its natural, raw state. But here, it refers to food which has been chemically changed by using additives* such as flavors, colors, preservatives*, stabilizers*, etc., or which has been combined with other foods in a manufacturing process. Generally speaking, if the ingredients* aren't “natural,” then we consider it to be ( 3 ). Drewnowski found that a dollar could buy 1,200 calories of cookies or potato chips, which are typical processed foods, but only 250 calories of carrots. Looking for something to wash down those chips, he discovered that his dollar bought 875 calories of soda (a processed food) but only 170 calories of orange juice. 5 As a rule, processed foods are more “energy dense*” than fresh foods: they contain less water and fiber but more added fat and sugar, which makes them both (4)less filling and more fattening. 5 These particular calories also happen to be the least healthful ones in the marketplace, which is why we call the foods that contain them "junk*.” Drewnowski concluded that the rules of the food game in America are organized in such a way that if you are eating (6) on a budget, the most rational economic strategy is to eat badly-and get fat.

3. Answer the following questions. 1 What is the difference between UNIX and Linux? 2 3 4 Choose one of the words in italics in the text. What is the definition of the word you have chosen? What are the three levels of a Linux system? What are the two main functions of the kernel? [Reading Text] UNIX was initially developed by researchers at Bell Labs in the 1970s. Today, UNIX and its variants are widely used mainly on servers. By far, the most well- known UNIX-like operating system is Linux. Linux is available in different distributions which include the Linux kernel and different collections of software. These distributions have various user interfaces, many experienced users preferring the command-line interface, or shell. Linux distributions include a range of software including text editors. memory. While the mechanics of Linux and other Unix operating systems are complicated, the components of a Linux system can be grouped into three levels. The lowest level is the hardware, such as Central Processing Unit (CPU) and The next level is the kernel. It enables communication between hardware and software, by providing instructions to the CPU and other hardware. The programs that are running on the system, or processes, make up the top level known as the user space. Processes in user space generally only have access to a restricted amount of memory and operations, this is called user mode. The kernel runs in kernel mode which allows it unrestricted access to hardware resources. The kernel provides functions such as process management and memory management. A computer only has limited Random Access Memory (RAM) and processor cores. Process management allows the system to run multiple programs (processes) at the same time even if the CPU can only execute only a few processes at a time. Memory management allows applications to share the system's memory while avoiding potential issues such as memory leak. Included with the kernel are device drivers that provide an interface for applications to communicate with hardware, such as hard drives. System calls allow user processes to access features that are executed at kernel mode, for example creating new processes.
