Smile Is the grammar of this sentence correct?
I can not understand the last sentence in this text . "This article is a review of the current understanding of tidal energy resources in the context of the emerging technology of tidal stream power generation. The geographical focus is on the north-west European continental shelf, the scope of a number of published reports on exploitable tidal stream energy resources. These estimates are reviewed as are some analytical models of energy extraction by tidal stream generators." Why use the second "are" ?Is the grammar of it correct? Please help me.
