Text: Considering that 4 GWe of scrubber capacity is either being built or recently constructed, it is conservatively assumed than an additional 6 GWe could be completed by 2005.
Entailment: It's thought that at least 6GWe of extra capacity might be added by 2005.
Contradiction: Since only 2 GWe of additional scrubber capacity is being built, it is unlikely total capacity will increase in the near future.
