Sample Solution:

-- This query selects all columns from the 'nobel_win' table.
SELECT *
-- Specifies the table from which to retrieve the data (in this case, 'nobel_win').
FROM nobel_win
-- Filters the rows to only include those where the 'year' column has a value greater than 1972
-- and the 'winner' column has values 'Menachem Begin' or 'Yitzhak Rabin'.
WHERE year > 1972
  AND winner IN ('Menachem Begin', 'Yitzhak Rabin');

Output of the Query:

year	subject	winner		country	category
1978	Peace	Menachem Begin	Israel	Prime Minister
1994	Peace	Yitzhak Rabin	Israel	Prime Minister

Code Explanation:

The above SQL query retrieves all columns from the 'nobel_win' table where the year of the award is greater than 1972 and the winner's name is either "Menachem Begin" or "Yitzhak Rabin". The query will return all rows that match these criteria, resulting in a list of all Nobel Prizes awarded after 1972 to either Menachem Begin or Yitzhak Rabin. The IN operator allows to check if a value is within a set of values, in this case the query will filter for rows where the winner column is either Menachem Begin or Yitzhak Rabin
