Answer:
Single User OS.
Explanation:
An operating system is a system software pre-installed on a computing device to manage or control software application, computer hardware and user processes.
This ultimately implies that, an operating system acts as an interface or intermediary between the computer end user and the hardware portion of the computer system (computer hardware) in the processing and execution of instructions.
Some examples of an operating system on computers are QNX, Linux, OpenVMS, MacOS, Microsoft windows, IBM, Solaris, VM etc.
There are different types of operating systems (OS) used for specific purposes and these are;
1. Batch Operating System.
2. Multitasking/Time Sharing OS.
3. Multiprocessing OS.
4. Network OS.
5. Mobile OS.
6. Real Time OS .
7. Distributed OS.
8. Single User OS.
A Single User OS is a type of operating system that only allows one user to perform a task or use a system at any time.
In this scenario, you are working with an online tech service to fix a problem with installation of a program on your machine. You grant them remote access to your computer to enable them to act as you to fix situation. Therefore, the type of OS which must be installed on your machine to allow this type of action by another person is called a Single User OS.

Answer:
1.word = "George slew the dragon"
startIndex = word.find('dr')
endIndex = startIndex + 4
drWord = word[startIndex:endIndex]
2. sentence = "Broccoli is delicious."
sentence_list = sentence.split(" ")
firstWord = sentence_list[0]
Explanation:
The above snippet is written in Python 3.
1. word is initialized to a sentence.
Then we find the the occurence of 'dr' in the sentence which is assign to startIndex
We then add 4 to the startIndex and assign it to endIndex. 4 is added because we need a length of 4
We then use string slicing method to create a substring from the startIndex to endIndex which is assigned to drWord.
2. A string is assigned to sentence. Then we split the sentence using sentence.split(" "). We split based on the spacing. The inbuilt function of split returns a list. The first element in the list is assigned to firstWord. List uses zero based index counting. So. firstWord = sentence_list[0] is use to get first element.
