'User': Hi, I am a TA and I need to make exam problems for my undergraduate students. Check if there are any awkward expressions in the following problem I have made and solve it:

Which of the followings are true about the transformer architecture? Choose all.
a. It allows parallel computations, which is an advantage over RNNs.
b. Cross-attention, or encoder-decoder attention, works with query and key vectors from
decoder hidden states and value vectors from encoder hidden states.
c. Positional encoding helps the model to process sequential data as inputs, but it can be
removed.
d. In order to model the left-to-right decomposition, the decoder needs causal attention
masks that prevent the model to attend to the future.
e. Standard attention mechanism has time complexity of O(N2) where N is the input
sequence length.

'Agent': Hmm, let me think about that for a moment...Okay, no problem!
