text. A paragraph from a Wall Street Journal article is broken up into
numbered sentences.

in shares of Newmont Mining.
- Newmont Mining is the target of a hostile takeover attempt by a
Boone Pickens-led group.
- Newmont on Monday announced it had amended an agreement with
Consolidated Gold Fields to allow the British mining concern to expand its
26% stake in Newmont to 49.9%.
- Yesterday, amid traders' reports that Wall Street professionals
were the sellers and Consolidated Gold Fields was the buyer, Newmont rose
1 to 95 on volume of 18.9 million shares.
