Q: I made the suggestion about not needing them on the ceiling into a stern warning. If you install them on the ceiling (unless they're specifically designed for it - most aren't) it could be deadly. = incorrect Carbon monoxide is not heavier than air - in fact it is slightly lighter as CO has the RMM of 28 whereas air is slightly more than this. It is therefore almost neutral density. However in a normal room, thermal convection current dominate transport of gases in a room. The ceiling is a relatively good place to have a CO detector as long as air flow from convectional currents in not affected and any boundary layer is overcome.
Can we conclude that is carbon monoxide (co) lighter than air?
A: yes

Q: ''Diane'' is co-written and recorded by American country artist Cam and is the lead single from her second album. The song was written with Tyler Johnson and Jeff Bhasker, who also produced the track. ''Diane'' is a country pop song that flips the script on Dolly Parton's country classic ''Jolene''.
Can we conclude that is diane by cam a response to jolene?
A: yes

Q: Natural brown sugar, raw sugar or whole cane sugar are sugars that retain a small to large amount of the molasses from the mother liquor (the partially evaporated sugar cane juice). Based upon weight, brown cane sugar when fully refined yields up to 70% white sugar, the degree depending on how much molasses remained in the sugar crystals, which in turn is dependent upon whether the brown sugar was centrifuged or not. As there is more molasses in natural brown sugar, it contains minor nutritional value and mineral content. Some natural brown sugars have particular names and characteristics, and are sold as turbinado, demerara or raw sugar if they have been centrifuged to a large degree. Brown sugars that have been only mildly centrifuged or unrefined (non-centrifuged) retain a much higher degree of molasses and are called various names across the globe according to their country of origin: e.g. panela, rapadura, jaggery, muscovado, piloncillo, etc.
Can we conclude that is brown cane sugar the same as brown sugar?
A: no

Q: As the governing body of association football, FIFA is responsible for maintaining and implementing the rules that determine whether an association football player is eligible to represent a particular country in officially recognised international competitions and friendly matches. In the 20th century, FIFA allowed a player to represent any national team, as long as the player held citizenship of that country. In 2004, in reaction to the growing trend towards naturalisation of foreign players in some countries, FIFA implemented a significant new ruling that requires a player to demonstrate a ''clear connection'' to any country they wish to represent. FIFA has used its authority to overturn results of competitive international matches that feature ineligible players.
Can we conclude that do you have to be born in the country you play for in world cup?
A:
no
