Here is a bar plot with the following categories: “twitter”, “YouTube”, “WeChat”, “Spotify”, “CNN”. Each category has its corresponding value. Here is a complex question about it, which can be answered by decomposing into several extractive questions.

Question: what is the sum of “WeChat” and “Twitter”? 
Answer: ans=ans_1+ans_2
ans_1=what is the value of “WeChat”? 
ans_2=what is the value of “Twitter”?

Question: what is the NAME_1 value of “WeChat”, “Spotify” and “Twitter”? 
Answer: ans=NAME_1(ans_1, ans_2, ans_3)
ans_1=what is the value of “WeChat”? 
ans_2=what is the value of “Spotify”?
ans_3=what is the value of “Twitter”?

Here is a new plot with the following categories: “Llama”, “tmp”, “MMD”, “GTX”. Each category has its corresponding value. For this new plot, generate more complexed questions and its decomposed answers similar to the examples.
