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_2t1BhVT):
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: "how"

Question 1 (Question id: q_NkfmJ):
Calculate 6 - 7 - -2.

Question 2 (Question id: q_cu2BfPA):
Solve for t: 15*t + 24 = 294 Respond with an integer.

Question 3 (Question id: q_FXNcsytn):
Calculate 1 - 1 * -9.

Question 4 (Question id: q_ZdPt):
Determine the value of i that satisfies: 140*i - 6 = 1254 Respond with an integer.

Question 5 (Question id: q_PGYgNET):
How many times does the letter "t" appear in the text: "at the call"? Respond with an integer.

Question 6 (Question id: q_Ryls):
Determine the value of s that satisfies: 9*s = 90 Respond with an integer.

Question 7 (Question id: q_gc0tnK7):
How many times does the letter "f" appear in the text: "And for what"? Respond with an integer.



Produce a JSON object whose top-level keys are the question ids.

For every question id, supply an object whose 'answer' field stores the solution.
Include an 'answer_type' field (value 'string' or 'integer') for every answer object.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
• num_questions_asked – total number of questions originally shown.

Now provide the result JSON using the described format.
