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_LvdVNhB):
Find the value of c in the equation: 10 - 16*c = -150 Respond with an integer.

Question 1 (Question id: q_NGdl):
How many times does the letter "f" appear in the text: "those from Mars"? Respond with an integer.

Question 2 (Question id: q_T92LGq4W):
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: "and"

Question 3 (Question id: q_Nhxn7):
Your task is to count how many legs there are in total when given a list of animals.

Now, how many legs are there in total if you have 4 insects, 2 lobsters, 4 beetles, 2 crickets?
 Respond with an integer.



Return a JSON with each question id (except for q_NGdl) as a key.

The value for each key should be an object that contains the answer in the field 'answer'.
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 string answers, include 'first_char' with the answer’s initial letter.
For last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.

{"ground_truth": {"q_T92LGq4W": {"answer": "d", "answer_type": "string", "first_char": "d", "original_string": "and"}, "q_LvdVNhB": {"answer": 10, "answer_type": "integer", "half_answer": 5}, "q_Nhxn7": {"answer": 80, "answer_type": "integer", "half_answer": 40}}}
