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_pfZO00):
Calculate ( 7 - 2 ).

Question 1 (Question id: q_pfZO00):
Calculate ( 7 - 2 ).

Question 2 (Question id: q_4pb7eXr):
Find the value of q in the equation: 10*q = 200 Respond with an integer.

Question 3 (Question id: q_ydmZ2):
Determine the value of e that satisfies: 24*e + 9 = 441 Respond with an integer.

Question 4 (Question id: q_1SdLH2Mr):
Calculate 6 * 3 - 3.

Question 5 (Question id: q_LdSJ):
How many times does the letter "u" appear in the text: "Furthermore each"? Respond with an integer.

Question 6 (Question id: q_cfkbgZY):
Determine the value of i that satisfies: 4*i - 1 = 47 Respond with an integer.

Question 7 (Question id: q_tEWHS):
Calculate 8 * 4 + 1.



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

The value for each key should be an object that contains the answer in the field 'answer'.
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).
If the response to a question is a string, add a 'first_char' field containing its first character.
For last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.
