a sample of liquid benzene at 70ºC and a sample of gaseous benzene at 90ºC

a sample of liquid benzene at 80ºC and a sample of gaseous benzene at 80ºC
a sample of liquid benzene at 80ºC and a sample of gaseous benzene at 80ºC

two samples of liquid benzene, one at 70ºC and the other at 80ºC
two samples of liquid benzene, one at 70ºC and the other at 80ºC

two samples of gaseous benzene, one at 80ºC and the other at 90ºC
two samples of gaseous benzene, one at 80ºC and the other at 90ºC

The answer is c) tons

In order to understand the problems of unwanted infertility in a country — the gambia — where the desire for children and the fertility is very high, a population-based survey was undertaken. all infertile women in 24 randomly selected enumeration areas were assessed. the study included a review of the problems faced and coping mechanisms employed by infertility clients and types of health care available for infertile couples in the different types and levels of the formal and traditional health system. half of the infertile couples failed to seek formal health care, and they have to reach a certain level of care in order to be properly managed. alternative care is often sought. child fostering is also a frequent solution to childlessness. in-depth interviews revealed that traditional care like healers and spiritual leaders are frequently consulted long before formal health care. this delay could be a problem in those cases where infertility is caused by infections.
