Answer:
Finding kth element is more efficient in a doubly-linked list when compared to a singly-linked list
Explanation:
Assuming that both lists have firs_t and last_ pointers.
For a singly-linked list ; when locating a kth element, you have iterate through a number of k-1 elements which means that locating an element will be done only in one ( 1 ) direction
For a Doubly-linked list : To locate the Kth element can be done from two ( directions ) i.e. if the Kth element can found either by traversing the number of elements before it or after it . This makes finding the Kth element faster because the shortest route can be taken.

Answer:
The circular individually linked list is more efficient for time sharing process ,when multiple application are running on pc it is responsibility of an output system to put all process on a list and execute them all by giving them piece of time and make them wait when cpu is selected to other process.
It will be more suitable for output system to use circular list as when it reaches to last of list it will be manually reaches to starting node or process.
Singly circular linked list is used when we are concerned with the memory as only one process will be allocated memory at once and there are no chances of process to go never-ending waiting.

Python code is explained below
Explanation:
# decorator.py starts
def uppercase(fcn):
def wrapper():
original = fcn;
modified = str(fcn).upper() ;
return modified;
return wrapper();
# decorator.py ends
# greet.py starts
import decorator #to generate the decorator
def greetings(): #invokes the greetings function for output
print("Hello");
print(decorator.uppercase(greetings));
# greet.py ends
Answer:
B. Immediately close the valve in the service line and charge the system
Explanation:
The precaution should be taken prior to recovering refrigerant from a chiller are:
1) Immediately disconnect the recycling or recovery equipment and open the system for service.
2) Wait for at least a few minutes to see if the system pressure rises, indicating that there is still refrigerant in liquid form or in the oil.
