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_lmDkWup):
How many times does the letter "t" appear in the text: "ago its"? Respond with an integer.

Question 1 (Question id: q_STfuvMD):
How many times does the letter "t" appear in the text: "the same"? Respond with an integer.

Question 2 (Question id: q_bjFFLSa8):
Solve for b: 18*b = 72 Respond with an integer.

Question 3 (Question id: q_AJmF):
Determine the value of b that satisfies: 104*b = 624 Respond with an integer.

Question 4 (Question id: q_P7GXV):
Calculate -9 + 5 + 9.



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

The value for each key should be an object that contains the answer in the field 'answer'.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
For last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.
