Für welche Bonds entscheiden

Hallo, 

ich bin verwirrt von einer Aufgabe: 

"You are deciding on whether to buy a one-year bond now, and another one-year bond in a year from now or whether instead just to buy a two-year bond The interest rate on a one-year bond is 4%, next year the interest rate on a one year bond will be 10%.
The interest rate on a two year bond purchased today is 5%. 
Clearly explain which scenario you will be better off taking the first action? The second action?" 
Das war`s. Ich weiß sogar nicht, womit ich anfangen soll, da ja weder einen Marktzins, noch Bondpreise vorgegeben sind. 
Bitte helfen! 

Danke
