Problem: Text: Frontal fog forms near a front when raindrops, falling from relatively warm air above a frontal surface, evaporate into cooler air close to the Earth's surface and cause it to become saturated.

Question: can there be rain and fog at the same time?
A: yes

Problem: Text: The crista ampullaris itself is a cone-shaped structure, covered in receptor cells called ''hair cells''. Covering the crista ampullaris is a gelatinous mass called the cupula. Upon angular acceleration (rotation), the endolymph within the semicircular duct deflects the cupula against the hair cells of the crista ampullaris. The hair cells respond by stimulating neurons that innervate them.

Question: is a structure found in the crista ampullaris?
A: no

Problem: Text: A soccer-specific stadium typically has amenities, dimensions and scale suitable for soccer in North America, including a scoreboard, video screen, luxury suites and possibly a roof. The field dimensions are within the range found optimal by FIFA: 110--120 yards (100--110 m) long by 70--80 yards (64--73 m) wide. These soccer field dimensions are wider than the regulation American football field width of 53 yards (48.8 m), or the 65-yard (59 m) width of a Canadian football field. The playing surface typically consists of grass as opposed to artificial turf, as the latter is generally disfavored for soccer matches since players are more susceptible to injuries. However, some soccer specific stadiums, such as Portland's Providence Park and Creighton University's Morrison Stadium, do have artificial turf.

Question: is a fifa soccer field bigger than a football field?
A:
yes
