will she perform more?
Erreichen oder Leisten?
Depends on the context. So both should be possible.
Difference with "tun" or "machen"' ? :)
Why not 'them'?
"Wird" is singular. If "sie" meant "they" here, the verb would be plural: "werden".
I thought leisten means to afford , or is it the reflexive form that means that?
Doesn't leisten also mean 'to supply'. So this could be "Will she supply more"?
