In 2003, a then-nascent Internet search engine developed an indexing algorithm called G-Cache that retrieved and stored X million webpages per hour. At the same time, a competitor developed an indexing algorithm called HTML-Compress that indexed and stored Y million pages per hour. If both algorithms indexed a positive number of pages per hour, was the number of pages indexed per hour by G-Cache greater than three times the number of pages indexed by HTML-Compress?
1)On a per-hour basis in 2003, G-Cache indexed 1 million more pages than HTML-Compress indexed
2)HTML-Compress can index between 400,000 and 1.4 million pages per hour
