Grammar challenging question. (Gerund phrase) Hi guys, how are you going? Thanks for reading in advance. I have difficulty to identify whether the sentence is a simple or compound sentence. Europe has long benefited from a dense railway network and is the world leader in the supply of railway systems. Employing 1 million people in rail operations and another 250,000 in manufacturing, the European railway sector has a 60% share of the world market and an annual turnover of $95 billion. Another question is that can the sentence be either a form of the followings? 1) The European railway sector has a 60% share of the world market and an annual turnover of $95 billion and employ 1 million people in rail operations and another 250,000 in manufacturing. 2) The European railway sector has a 60% share of the world market and an annual turnover of $95 billion employing 1 million people in rail operations and another 250,000 in manufacturing.
