In this task, you are given commands (in terms of logical operations) to select relevant rows from the given table. Your job is to generate a natural language interpretation of the given command. 
 Here are the definitions of logical operators: 
 1. count: returns the number of rows in the view 
 2. only: returns whether there is exactly one row in the view 
 3. hop: returns the value under the header column of the row 
 4. and: returns the boolean operation result of two arguments 
 5. max/min/avg/sum: returns the max/min/average/sum of the values under the header column 
 6. nth max/nth min: returns the n-th max/n-th min of the values under the header column 
 7. argmax/argmin: returns the row with the max/min value in header column 
 8. nth argmax/nth argmin: returns the row with the n-th max/min value in header column 
 9. eq/not eq: returns if the two arguments are equal 
 10. round eq: returns if the two arguments are roughly equal under certain tolerance 
 11. greater/less: returns if argument 1 is greater/less than argument 2 
 12. diff: returns the difference between two arguments 
 13. filter eq/not eq: returns the subview whose values under the header column is equal/not equal to argument 3 
 14. filter greater/less: returns the subview whose values under the header column is greater/less than argument 3 
 15. filter greater eq /less eq: returns the subview whose values under the header column is greater/less or equal than argument 3 
 16. filter all: returns the view itself for the case of describing the whole table 
 17. all eq/not eq: returns whether all the values under the header column are equal/not equal to argument 3 
 18. all greater/less: returns whether all the values under the header column are greater/less than argument 3 
 19. all greater eq/less eq: returns whether all the values under the header column are greater/less or equal to argument 3 
 20. most eq/not eq: returns whether most of the values under the header column are equal/not equal to argument 3 
 21. most greater/less: returns whether most of the values under the header column are greater/less than argument 3 
 22. most greater eq/less eq: returns whether most of the values under the header column are greater/less or equal to argument 3

Question: eq { count { filter_eq { all_rows ; joined ; 2007 } } ; 2 } = true

Answer: select the rows whose joined record is equal to 2007 . the number of such rows is 2 .


Question: less { hop { filter_eq { all_rows ; player ; eric king } ; round } ; hop { filter_eq { all_rows ; player ; lionel gates } ; round } } = true

Answer: select the rows whose player record fuzzily matches to eric king . take the round record of this row . select the rows whose player record fuzzily matches to lionel gates . take the round record of this row . the first record is less than the second record .


Question: and { eq { diff { hop { filter_eq { all_rows ; winner ; thomas wassberg } ; fis nordic world ski championships } ; hop { filter_eq { all_rows ; winner ; gunde svan } ; fis nordic world ski championships } } ; -9 } ; and { eq { hop { filter_eq { all_rows ; winner ; thomas wassberg } ; fis nordic world ski championships } ; 1980 } ; eq { hop { filter_eq { all_rows ; winner ; gunde svan } ; fis nordic world ski championships } ; 1989 } } } = true

Answer:
select the rows whose winner record fuzzily matches to thomas wassberg . take the fis nordic world ski championships record of this row . select the rows whose winner record fuzzily matches to gunde svan . take the fis nordic world ski championships record of this row . the second record is 9 larger than the first record . the fis nordic world ski championships record of the first row is 1980 . the fis nordic world ski championships record of the second row is 1989 .
