Lorazepam is commonly given along with a neuroleptic agent. what is the purpose of administering the drugs together?

Neuroleptics are molecules that act on the nervous system by modulating both agitation and neuronal activity. These drugs have an effect countering the transmission of a neuromediator.

These side effects are numerous, among them there is tardive dyskinesia, including akathisia (a state of agitation, distress, and restlessness). This can be corrected by the administration of benzodiazepines such as lorazepam.

phylogenetic tree is the tree of life or evolution tree. it shows the different branches of evolution. the sequence goes like tissues - coelom - backbone - endoskeleton - segmentation

you didn't give any options but heres what i can tell you: an inference is likely to change based on additional observations. the latter is something that you have seen or sensed using your sensory organs while the former is like a conclusion out from what you have observed.
