From what I understand, you mean when the dollar's value increases on the open market. This means that it takes more of a currency to get to 1 USD. Take Thai Baht for example (THB). Typically, it takes approx. 30 THB to get to 1 USD. So when the value of the USD rises, it can take up to 36 THB to get to 1 USD. Make sense?
Duty to protect is the correct answer.
According to the Psychologists Code of Ethics, mental health professionals have a duty to protect. This duty to protect is the therapist's responsibility to break confidentiality (even without client's consent) when they find it necessary to protect the clients from hurting themselves and/or others from getting harmed at the hands of these clients.
Yes it is, because it starts with a conjunction.
