Hello dear teachers.
someone asked me about the mistakes in the following sentences but I could not find any mistake:
1- Each river and ravine create an obstacle in the cross-country race.
2-The execution of exquisite decoration and the effective use of space, light,and water contributes to the Alhambra's unique beauty.
Thanks in advance.
Once again we have two great minds coming up with the same thoughts at the same time.
Thanks a lot Bhai and fivejedjon :)
1. It depends on whether river and ravine are regarded as a tied together combination. If tied together effectively as a single subject then 'creates' singular would be correct. If you mean river and ravine are mutually exclusive and hence regarded as plural subjects, then 'create' is correct.
2. This is similar. Are you talking about the combination of space light and water, if so 'contributes', otherwise 'contribute'
