There's supposedly some "alternative" way to make it zoom in/out by holding and then moving up/down, but I can't get it to work.
To zoom with one hand, do a double-tap, and upon the second tap, hold. Then slide down to zoom in and up to zoom out.
i.e. tap, tap+hold... (while holding) slide up/down
As to why there are so many more good men chess players compared to women? I don't know.
Yes, but OPEC doesn't control the bulk of the oil out there.
"Majority" is used for countables. Use "bulk" for uncountables.
