We extend a result of Arthur Apter which answer a question of Matthew Foreman
and Menachem Magidor related to mutually stationary sets. We also extend a
result of Arthur Apter which answer a question of W. Hugh Woodin and prove a
conjecture by Ioanna Dimitriou. Simultaneously, we study different symmetric
extensions based on Levy Collapse where for a cardinal $\kappa$, $DC_{\kappa}$
either holds or fails. Further, we observe the relationship of the fat diamond
principle and other L-like properties with level by level equivalence between
strong compactness and supercompactness.
