From Siberia, the mammoth was sent to the Netherlands and Japan. Scientists there studied it in detail. Studies of her teeth and tusks showed she was just one month old when she died. Research has also shown us the sequence of events that led to her death. Lyuba fell and killed near a muddy river. The mud helped keep her body frozen until she was found 4000 years later. Scientists hope that further studies will help explain how mammoths like lyuba lived. They also want to know why mammoths became extinct. 17- from the paragraph above, the passive sentences are ....a. the mammoth was sent to the Netherlands and Japan.
b. They also want to know why mammoths became extinct
c. Scientists there studied it in detail
d. she was found 4000 years later​

A. the mammoth was sent to the netherlands and japan.

explanation : it is passive sentence because : the subject is not doing the verb, and the action of the verb is done to the subject.

Hope it helps!
