United Spirits Limited, abbreviated to USL, is an Indian alcoholic beverages company, and the world's second-largest spirits company by volume. It is a subsidiary of Diageo, and headquartered at UB Tower in Bangalore, Karnataka. USL exports its products to over 37 countries.
USL exports its products to 38 countries.
The context states that USL exports its products to over 37 countries, but doesn't specify an exact number. I think that the system had trouble with this because it failed to consider the word "over."
