original: The possibility remained that liquid ethane and methane might be found on Titan's poles, where it was expected to be abundant and stable.
simplifications: it is possible that an a large stable amount of liquid ethane and methane might be on Titan's poles. It is possible that liquid ethane and methane might be found on Titan's poles. It was expected to be a lot of it there. Ethane and Methane gases are supposedly stable and abundant on Titan's poles. Liquid ethane and methane might be discovered on Titan's poles. The possibility hasn't been ruled out. Both gases should be stable and available in large quantities. Liquid ethane and methane could have still existed on Titan's poles. There, it was expected to be plentiful and stable. Liquid ethane and methane might be found on Titan's poles. It was expected to be abundant and stable. It was still possible to find a large stable source of liquid ethane and methane on the poles of Titan. It was still possible that liquid ethane and methane could be found on Titan's poles. Liquid ethane and methane might be found on Titan's poles. It was expected to be abundant and stable. The chance lasted that liquid ethane & methane might be on Titan's poles, where it was expected to be plentiful and solid.
