1.For which of the following situations is a nested loop needed? Assume that no procedure is used. It is a Multiple Select Question (MSQ).

To find the number of authors who have written a book in “French” in 2007 from the “Library” dataset.

To find the number of pair of students who have scored the same Physics marks from the “Scores” dataset

To find the number of players who have won the medal in “Wrestling” from the “Olympics” dataset

To find the number of students with at least two vowels in their name from the “Scores” dataset.

2. The following pseudocode is executed using the “Words” dataset. Assume that length(x) is a procedure that returns the number of letters present in a word x. What will A represent at the end of the execution?

Number of students whose names are without vowels

Number of students whose names have at most one vowel

Number of students whose names have exactly one vowel

Number of students whose names have at least one vowel

3. The following pseudocode is executed using the “Library” dataset. What will C represent at the end of the execution? Assume that there is only one row corresponding to each author in the “Library” dataset.

Number of authors who have written different genre books in same language

Number of pairs of authors who have written different genre books in same language

Number of authors who have written same genre books in different language

Number of pairs of authors who have written same genre books in different language

Number of vowels are same in both the words
Number of consonants are not same in both the words
The given pseudocode is executed using the “Words” dataset. The variable count in the given pseudocode counts the number of special pairs. Choose the correct code fragment to complete the pseudocode.

The following pseudocode is executed using the “Scores” dataset. The variables M, P and C store the number of students in Mathematics, Physics and Chemistry clubs respectively.

Physics

Chemistry

Mathematics

The student cannot join any club

Yes, if the student has scored more than 90 marks in at least two subject

Yes, if the student has scored more than 90 marks in Mathematics and Chemistry

Yes, if the student has secured more than 90 marks and the same marks in Mathematics and Chemistry

No, a student cannot join more than one club

he given pseudocode is executed using the “Shopping Bills” dataset. frac stores the ratio of the number of customers who purchased both “Soap” and “Facewash” to the number of customers who purchased “Facewash”. Choose the correct code fragment to complete the pseudocode. (Assume there is at least one customer who has purchased “Facewash”).

8. The following pseudocode is executed using the “Olympics” dataset. At the end of the execution, A, B and C store the number of pairs of players from the same nation who have won same medal in different year. Assume that one player has won only one medal. Choose the correct code fragment(s) to complete the pseudocode. It is a Multiple Select Questions(MSQ)

correct answer
