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_6I98PnSt):
Find the value of f in the equation: 19 - 16*f = -301 Respond with an integer.

Question 1 (Question id: q_Miq1gR):
Determine the value of m that satisfies: 130 - 10*m = 90 Respond with an integer.

Question 2 (Question id: q_ObLLUc3W):
How many times does the letter "t" appear in the text: "seems is the"? Respond with an integer.

Question 3 (Question id: q_M7qb6kQ):
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: "of"

Question 4 (Question id: q_7VD6):
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 lions, 1 starfish, 2 cockroachs?
 Respond with an integer.

Question 5 (Question id: q_ZmgM6rfz):
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 wasps, 4 lions, 2 tigers, 2 snakes?
 Respond with an integer.

Question 6 (Question id: q_TTaE7Eac):
Find the value of j in the equation: 6*j + 23 = 83 Respond with an integer.



Output JSON where all question ids are keys, omitting q_Miq1gR, q_6I98PnSt, q_7VD6.

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.
When counting animal legs, include an 'animal_types' list of the distinct animal names (singular, sorted).

Now provide the result JSON using the described format.
