From the five statements presented under the question, two that present development on the theme mentioned at the beggining are to be considered correct:
2. Michelle decides to join Erkan in his own world instead of avoiding him.
3. Erkan's face brightens in a smile as soon as Michelle rushes to his side.
Statement #2 implies that Michelle learned enough from Erkan's history and personality, and despite any possible misconceptions, she ended up sympathizing with him. Thus, a hanging bond was created from Michelle's side.
Statement #3 has a connection with statement #2, explaining Erkan's reaction towards Michelle's act of affection, finally inferring Michelle's bond of trust was joined from Erkan's side.
Statements #1 and #5 cannot be considered correct, given the lack of confidence Erkan demonstrates towards the people surrounding him at the nursing home.
Statement #4 presents no bond creation, rather an event occurred during Erkan's lifetime.
