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_Uj1F):
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: "also"

Question 1 (Question id: q_cXNwzD6):
Calculate 9 - -4.

Question 2 (Question id: q_lko5Ig4):
How many times does the letter "a" appear in the text: "has often"? Respond with an integer.

Question 3 (Question id: q_He2VHCjc):
How many times does the letter "n" appear in the text: "General Terms"? Respond with an integer.



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

For every question id, supply an object whose 'answer' field stores the solution.
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.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
• num_questions_asked: how many questions were asked in total.
• num_questions_answered – number you actually answered.
'questions_with_integer_answers' should enumerate every id whose answer is an integer.

Now provide the result JSON using the described format.
