issues on the environment and human rights.
When he was injured in an equestrian competition, he was left paralyzed
from the next down. Drawing strength
from his wife and family, Reeve chose to live his life. But it wasn’t just that
that made Reeves heroic. He remembered
the other patients who were also undergoing rehab and saw their struggles to be
able live life again and realize that there was something he could do despite
his injury. He devoted his time to lobby
for better research on spinal cord injuries using his status as a celebrity to
work on that goal and through his efforts the Christopher and Dana Reeves
Foundation was established. Thanks to
Reeve’s supervision, spinal research has improved and he continued to speak
before Congress for more funding on improving the treatment and research of
spinal injury. Until their deaths both
Christopher and Dana worked on this and the Foundation has done a lot for
helping patients with spinal injury.</span>
Explanation: The sentence that is correctly punctuated is: B. Two main causes of orchid death include: overwatering and overpotting; however, too much sun can also cause a problem. It is correct because because before a sentence connector such as However there must be a full stop or a semi-colon. This is the case in sentence B while the other sentences have a comma before however. Commas are not used before conjuncts.
