Read the following code carefully.

Then, select the prompt that best describes what this program does.

• Counts how many total pairs of double letters appear across all words.

• Counts how many words contain at least one pair of consecutive identical letters.

• Counts the total letters in all words that appear twice in a row.

• Counts how many words have exactly two letters total.

• Counts how many letters repeat twice in total.

Answer explanation

💡 Brief Explanation

• The code checks each word for any two consecutive identical letters (word[i] == word[i + 1]).

• If such a pair exists, it increases count by 1 and breaks, ensuring each word only contributes once.

• For ["apple", "tree", "banana", "grape", "book"], the words with double letters are "apple", "tree", and "book".

• Output: 3

• Therefore, the function counts how many words contain at least one pair of consecutive identical letters.

Read the following code carefully.

Then, select the prompt that best describes what this program does.

• Returns the sum of all positive even numbers in the list.

• Returns the sum of all negative numbers in the list.

• Returns the sum of the absolute values of all negative even numbers.

• Returns how many even numbers appear in the list.

• Returns absolute value of all negative even numbers.

Answer explanation

💡 Brief Explanation

• The function loops through each number n in the list.

• It checks two conditions: n % 2 == 0 (even) and n < 0 (negative).

• If both are true, it adds the absolute value of that number (abs(n)) to total.

• For [4, -3, -6, 7, -8, 2, -9], the negative even numbers are -6 and -8.

• Their absolute values are 6 + 8 = 14. The function returns 14.

• So it correctly returns the sum of the absolute values of all negative even numbers.

What is the output of this code?

Answer explanation

💡 Brief Explanation

• The program starts with total = 0 and loops through nums.

• It skips negative numbers (-3) and stops when it hits the first zero (0).

• It adds only the positive numbers before the zero → 2 + 5 + 4 = 11.

• The loop then breaks at zero, so the remaining numbers (6) are never added.

What is the output of this code?

Answer explanation

💡 Brief Explanation

• The program loops through each word in word_list.

• For every word, it counts occurrences of "a".

• When it reaches a word containing "z", it breaks completely (stops checking any remaining words).

Code Trace:

• "apple" → 1 "a" → total = 1

• "banana" → 3 "a"s → total = 4

• "grape" → 1 "a" → total = 5

• "zebra" → 1 "a", but "z" triggers break after this word → total = 6

• "avocado" → not checked (loop already broken)
