Here is a set of basic questions producing integer or string outputs. Answer them and format the result precisely with the JSON instructions provided:

Question 0 (Question id: q_jWaqtWgd):
Solve for w: 91*w = 1547 Respond with an integer.

Question 1 (Question id: q_Qali7):
Calculate -5 + 8.

Question 2 (Question id: q_zN9sW):
How many times does the letter "w" appear in the text: "Hall way Why"? Respond with an integer.

Question 3 (Question id: q_22qs):
Your task is to count how many legs there are in total when given a list of animals.

Now, how many legs are there in total if you have 3 birds, 1 sheep, 2 snakes?
 Respond with an integer.

Question 4 (Question id: q_lDal5C):
Your job is to return the last character of a string as a string. For example, the last char of "hello" is "o". Return the last character of the following string: "what"



Your output must be a JSON mapping every question id to its answer info.

Each key’s value must be an object holding an 'answer' field.
If the response to a question is an integer that is even, add the field 'additional_answer_info' containing 'half_answer' (answer ÷ 2) and 'double_answer' (answer × 2).
For last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.
