Men ..... to abolish wars up to now, but maybe they will find a way in the future?
Explanation
- Men have never managed to abolish wars up to now, but maybe they will find a way in the future
- مرد اب تک کبھی بھی جنگوں کو ختم کرنے میں کامیاب نہیں ہوئے ہیں، لیکن شاید مستقبل میں انہیں کوئی راستہ مل جائے۔
- ...
- have never managed is correct as present perfect tense is used to indicate that an action has taken place once or more before now.
- The other options are wrong as ' up to now' indicates the use of the present perfect tense.
