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_VfksMv):
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: "and"

Question 1 (Question id: q_tUHK):
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: "way"

Question 2 (Question id: q_UnhzCb):
Find the value of n in the equation: 20 - 11*n = -167 Respond with an integer.

Question 3 (Question id: q_BKOmNEf):
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: "machines"



Return a JSON with each question id as a key.

Each key’s value must be an object holding an 'answer' field.
Also add the answer type as 'string' or 'integer' to the field 'answer_type' for each object.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
For last-character tasks, provide 'original_string' alongside the answer.

Add a top-level 'global_metadata' field that records overall stats:
'num_questions_asked' should equal the total questions that appeared.
Fill 'questions_with_integer_answers' with the ids of integer-answer questions (leave empty when none).

Also include 'combined_results' consisting of:
  • integer_info – object mapping ids to their integer answers
  • sum_of_answers – sum of those integers

Now provide the result JSON using the described format.
