1. Work out the logic in the following excerpt and select the correct answer
```If a = 2
and a = b
then a + b = ?```

1

4

3

2

2. Analyse the logic in the given excerpt to work out whether the conclusion is true or false.
```if a = 3
and b < a
and c > b
then c must be greater than 3. ```

TRUE

FALSE

3. The internet - that you probably use every day(!) - is …..

a large coordination of satellites in the international space station

a network of networks

All of the above

fourteen super computers in the USA that act as a high ground server

4. What is 3 in this base 2 language of XY?
```A new base 2 language uses only two symbols

X and
Y

Consider the following and answer the question:
XX = 0
XY = 1
YX = 2
What is 3 in this base 2 language of XY?```

YY

XXY

YYY

XXX

5. Why do computers only 'understand' 1s and 0s?

Because they are incapable of more complex calculations

Because they are ultimately made up of small circuits (switches) that can either be on or off

Because they deal in small packets and packets can only be either one or two in size

All of the above

8. What is the output for the following?
```There are two parallel roads, each containing N and M buckets, respectively. Each bucket may contain some balls.
The buckets on both roads are kept in such a way that they are sorted according to the number of balls in them.
Mr Moose starts from the end of the road which has the bucket with a lower number of balls(i.e. if
buckets are sorted in increasing order, then geek will start from the left side of the road).
The geek can change the road only at the point of intersection(which means, buckets with the same
number of balls on two roads). Now you need to help Mr Moose to collect the maximum number of balls.

Input:
The first line of input contains T denoting the number of test cases.
The first line of each test case contains two integers N and M, denoting
the number of buckets on road1 and road2 respectively. 2nd line of each
test case contains N integers, number of balls in buckets on the first road.
3rd line of each test case contains M integers, number of balls in buckets

Output:
For each test case output a single line containing the maximum possible balls that Mr Moose can collect.

Constraints:
1<= T <= 1000
1<= N <= 10^3
1<= M <=10^3
0<= A[i],B[i]<=10^6

Example:
Input:
1
5 5
1 4 5 6 8
2 3 4 6 9

What is the output? ```
