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_v1mIp):
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: "a"

Question 1 (Question id: q_n5Lv):
Find the value of b in the equation: 18*b - 21 = 105 Respond with an integer.

Question 2 (Question id: q_EuX023x):
Calculate -2 - -5.

Question 3 (Question id: q_BDAgHlcp):
How many times does the letter "a" appear in the text: "Donations to"? Respond with an integer.

Question 4 (Question id: q_DcjdW):
How many times does the letter "e" appear in the text: "And there"? Respond with an integer.

Question 5 (Question id: q_5UXH3J):
Solve for c: 13 - 19*c = -196 Respond with an integer.

Question 6 (Question id: q_yzdSW6):
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: "they"

Question 7 (Question id: q_7LsO0Rjt):
How many times does the letter "i" appear in the text: "have revolutionized agriculture"? Respond with an integer.



Output JSON where all question ids are keys, omitting q_BDAgHlcp, q_DcjdW, q_7LsO0Rjt.

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

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.
