Find the elements and how (they are / are they) constructed

Question

1. to find the key elements of these algorithms and how are they constructed.
2. to find the key elements of these algorithms and how they are constructed.

Which of the two sentence above is correct?

Answer 1

These are incomplete sentences, however the first one clearly has wrong word order: 'are they' is for an interrogative sentence and not for one with reported speech (find... how they are).
