What is the correct answer to number 6 ? explain why and answer this

I remember learning in my bio. class that since the oranges don't contain seeds, they cannot be cultivated normally. In order to be cultivated, a pipe is attached to a young citrus tree (a branch growing root, in this case) in order to connect the young orange tree to a full formed seedless orange tree. If the process of growth all goes well, the end result will be a tree w/ oranges without seeds ONLY since it was nurtured through a grown seedless orange tree.

events in order:

1.       vishnu schist

2. zoroaster granite

3. bass limestone

4. hakatar   shale

5. igneous intrusion

6. shinumo quartzite

7. dox sandstone

8. tapeats limestone

9. bright angel shale

10. muav limestone

11. temple butte limestone

12. redwall limestone  

nonconformity

answer: the unkar group shows angular unconformity because the layers are turned at angle.

unconformity

answer: specifically the angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled. an angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled.

disconformity

answer: the disconformities aremarked irregular lines between the sedimentaryrocks layers.
