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_VC01L):
How many times does the letter "i" appear in the text: "in paragraph"? Respond with an integer.

Question 1 (Question id: q_5q67n2U):
Find the value of d in the equation: -2*d - 16 = -34 Respond with an integer.

Question 2 (Question id: q_hgqqEne):
Calculate -2 - -6 * 3.

Question 3 (Question id: q_KiKCju):
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: "microscopes"



Return a JSON with each question id as a key.

Each key’s value must be an object holding an 'answer' field.
If the response to a question is an integer that is even, also add the field 'half_answer' to the object which contains the answer integer divided by two.
For string answers, include 'first_char' with the answer’s initial letter.

Now provide the result JSON using the described format.

{"ground_truth": {"q_VC01L": {"answer": 1}, "q_5q67n2U": {"answer": 9}, "q_hgqqEne": {"answer": 16, "half_answer": 8}, "q_KiKCju": {"answer": "s", "first_char": "s"}}}
