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_y21757):
Calculate ( -6 - -7 ).

Question 1 (Question id: q_cf8WfC):
Find the value of f in the equation: f - 13 = -3 Respond with an integer.

Question 2 (Question id: q_rZrva0):
How many times does the letter "i" appear in the text: "of whole cities"? Respond with an integer.

Question 3 (Question id: q_nt6Gxy):
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: "like"

Question 4 (Question id: q_FK0qAI):
Determine the value of v that satisfies: 40 - 360*v = -320 Respond with an integer.

Question 5 (Question id: q_oJbCSbtD):
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: "one"



Output JSON where all question ids are keys, omitting q_cf8WfC.

For every question id, supply an object whose 'answer' field stores the solution.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
For string answers, include 'first_char' with the answer’s initial letter.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
Include 'num_questions_asked' to record the total number of questions presented.

Now provide the result JSON using the described format.
