Transformation of sentence

She was crying over the loss of her favourite stuffed toy.
She was crying because she had lost her favourite stuffed toy.

The above sentence is the answer given for transformation of the sentence in bold.

Am I correct to transform the bold sentence as follows?

She was crying because her favourite stuffed toy was lost.

Thanks.

It's fine. The first doesn't say who lost it.

Please give your threads more useful titles. All of them are transformations. You could call this one "the loss of" or something like that.

Thanks, Barb.

Am I right to say that both sentences are correct in transforminng the bold sentence?

The second one maintains the meaning of the bold. The first transformation says that she lost it. It might have been lost in a fire or when she loaned it to a friend who lost it. Those situations are possible in the bold sentence and in the second rewrite.
