Scrape contents from a website drop down selection result

I want to scrape the resulting data of drop down menu from below site: http://ift.tt/2foEQwU

I want to scrape the Vedic text that appears when a selection is made. There are several combinations of text based on drop down item selected.

I have tried using Google web scraper. But it does not support drop down menu selections.

Kindly help me in this.

PS: Will be helpful if you could solve it with a script in ubuntu, that can perform selections automatically and scrape the text.
