Definition: In this task, you will be given a set of steps that are required to answer a specific question. Your job is to generate that question. Each given step refers to either an entity (known or unknown), a propery of an entity or a query operation (count, group, union, etc.) Knowing those operations and how they appear in the input may help you generate more accurate questions.
 Select: A select step is used to return a set of objects. There are no references to previous steps in a select step. template: Return [attributes]
 Filter: A filter step is used to return results from a previous step to which a certain condition applies. template: Return [#step] [condition]
 Project: A project step should return certain attributes of the results of a previous step. template: Return [attributes] of [#step]
 Aggregate: An aggregate step returns an aggregator function applied on a step's result. template: Return the [aggregator] of [#step].
 Group: A group step is an aggregator applied on attributes. template: Return the [aggregator] of [#step] for each [attribute]
 Superlative: A superlative step is used to return the result with a highest/lowest attribute among other results. template: Return [#step1] [where] [#step2] [is] [highest / lowest]
 Comparative: A comparative step is used when we need to compare an attribute with a number to filter results. template: Return [#step1] [where] [#step2] [comparator] [number] 
 Union: A union step is used to return results of two steps together. template: Return [#step1] [or / ,] [#step2]
 Intersection: An intersection step returns the result that two steps have in common. template: Return [attribute] of both [#step1] and [#step2]
 Discard: A discard step returns result of a step and excludes result of another step from it. template: Return [#step1] besides [#step2]
 Sort: A sort returns result of another step in a specific order. template: Return [#step1] [ordered / sorted by] [#step2]
 Is true: An is true step checks a condition on another result and returns a true or false. template: Return [is / if] [condition]
 Arithmetic: An arithmatic step operates an arithmatic operation on one or more steps. template: Return the [arithmetic op.] of [#step1] [and] [#step2].

Positive Example 1 -
Input: #1 return secretaries 
#2 return #1 born in state 'Alabama 
#3 return departments managed by #2 
#4 return distinct creation years of  #3
Output: What are the distinct creation years of the departments managed by a secretary born in state 'Alabama'?

Positive Example 2 -
Input: #1 return flights  
#2 return #1 from baltimore 
#3 return #2 to  atlanta 
#4 return #3 that  arrive  before noon  
#5 return #1 from denver 
#6 return #5 to  atlanta 
#7 return #6 that  arrive  before noon  
#8 return #4 ,  #7
Output: I'd like to see flights from baltimore to atlanta that arrive before noon and i'd like to see flights from denver to atlanta that arrive before noon

Negative Example 1 -
Input: #1 return red objects 
#2 return #1 that  are metal 
#3 return blue objects 
#4 return #1 that  are rubber 
#5 return number of  #2 
#6 return number of  #4 
#7 return difference of #5 and #6
Output: How many more metal objects are there than rubber objects?

Negative Example 2 -
Input: #1 return Landmark Theatres 
#2 return Marcus Theatres 
#3 return screens of #1 
#4 return screens of #2 
#5 return number of  #3 
#6 return number of  #4 
#7 return the sum of #5 and #6
Output: How many screens do Landmark Theatres and Marcus Theatres have each?

Now complete the following example -
Input: #1 return items 
#2 return colors of #1 
#3 return number of  #1 for each #2 
#4 return #2 where #3 is one 
#5 return #1 where #2 is the  same as #4 
#6 return shape of #5
Output: 



Answer: What shape are the items that do not have another object of the same color?
What is the shape of the only item that doesn't have another item of the same color?
