Q: One lunation (an average lunar cycle) is 29.53 days. There are about 365.24 days in a tropical year. Therefore, about 12.37 lunations (365.24 days divided by 29.53 days) occur in a tropical year. In the widely used Gregorian calendar, there are 12 months (the word month is derived from moon) in a year, and normally there is one full moon each month. Each calendar year contains roughly 11 days more than the number of days in 12 lunar cycles. The extra days accumulate, so every two or three years (seven times in the 19-year Metonic cycle), there is an extra full moon. The extra full moon necessarily falls in one of the four seasons, giving that season four full moons instead of the usual three, and, hence, a blue moon.
Can we conclude that is there a month with two full moons?

A false awakening is a vivid and convincing dream about awakening from sleep, while the dreamer in reality continues to sleep. After a false awakening, subjects often dream they are performing daily morning rituals such as showering, cooking, cleaning, eating and using the toilet. False awakenings, mainly those in which one dreams that they have awoken from a sleep that featured dreams, take on aspects of a double dream or a dream within a dream. A classic example is the double false awakening of the protagonist in Gogol's Portrait (1835).
is it possible to dream in a dream?

Answer: yes
If f is differentiable at a point x, then f must also be continuous at x. In particular, any differentiable function must be continuous at every point in its domain. The converse does not hold: a continuous function need not be differentiable. For example, a function with a bend, cusp, or vertical tangent may be continuous, but fails to be differentiable at the location of the anomaly.

OPTIONS:
- no
- yes

if a function is continuous then it is differentiable at that point?

A: yes
Problem: Text: 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.

Question: is carbon monoxide (co) lighter than air?

OPTIONS:
- no
- yes
A: yes
IN: Is it true that are football boots and soccer boots the same?

Football boots, called cleats or soccer shoes in North America, are an item of footwear worn when playing football. Those designed for grass pitches have studs on the outsole to aid grip. From simple and humble beginnings football boots have come a long way and today find themselves subject to much research, development, sponsorship and marketing at the heart of a multi-national global industry. Modern ''boots'' are not truly boots in that they do not cover the ankle - like most other types of specialist sports footwear, their basic design and appearance has converged with that of sneakers since the 1960s.
