multiple choice - zadanie?

[0aleksandra0]

Mam zdanie:

The use of computers has meant students can study programmes at their own speed when and for how long they want - and no need to worry about the teacher having a favourite or doing ....?...... another boring lesson

moje pytanie brzmi dlaczego z czterech odpowiedzi:
a) still
b) for
c) yet
d) already
Yet jest poprawne?
Z góry dziękuję za pełne wytłumaczenie.

[xeo]

yet another tutaj znaczy jeszcze jedną nudną lekcję. Nic innego nie pasuje z another w tym kontekście.
