[EX Q]: [header] How to stay up late without electronics [title] Drink caffeine. [step] Caffeine blocks neurotransmitters in your brain that make you sleepy. When you start to feel drowsy, reach for a cup of coffee or a soda. <sep> (A) Remember that caffeine loses its effectiveness with overuse. Try to save it for when you really need it. (B) Your body will start shutting down caffeine when you're outside and keep you awake by doing what it is meant to do. It can help you stay awake long enough to go to bed. (C) Though caffeine will not give you energy right before sleep, it will trigger the natural sleep signal that draws us into the world right before it hits. An caffeine-rich beverage will wake you up more, making your sleep better. (D) Coffee is the source of human sleepiness so drinking coffee or another caffeinated beverage before bedtime is important. Even an extra pill is a key lubricant.

[EX Q]: [header] How to make a mimosa bar [title] Choose a few types of sparkling wine. [step] No mimosa is complete without the bubbly. Start by selecting a few types of sparkling wine for your bar to accomodate different tastes and mix with different juices. <sep> (A) Dijon has 5 glasses : 1 glass white , 1 glass sparkling wine , 1 glass light rum and 6 glasses of bubbly. Different juices add different flavors, but not an exact science. (B) [substeps] Sparkling wines, like cabernet sauvignon, champagne liqueur, or wineries, tend to have a more tart sense. Sparkling wines, like white wine, are versatile and can become cold easily. (C) Try wines like : [substeps] A cava or brut for a dry taste prosecco for a light but sweet flavor champagne for a rich and creamy flavor sparkling rose for floral and fruity notes [title] Figure out the amount of wine you need. [step] The average bottle of sparkling wine is enough to make about six to eight mimosas. (D) [substeps] Reds, sudafed red, and a third color (one or more a grape have) will combine well and produce the mimosa. Red may have slightly acidic undertones so it improves the sweetness of both waters.

[EX Q]: [header] How to find out if someone is divorced [title] Look for a wedding ring. [step] This is the simplest indicator of someone's marital status. A wedding ring is worn on the left ring finger, or the finger next to the pinkie. <sep> (A) Rings are usually somewhat bigger, with a big design, so if your wedding ring was worn more than 30 years ago it could still be a ring. [substeps] Rings are very small, and made of brightly colored material. (B) [substeps] Rings have a gold ring attached to them, and are made of plastic, so they are sometimes worn by people divorced to save money or to help maintain them from damage. Marriage rings have a thin ring attached to them with rubber bands that hold the ring in place, but they are also not extended. (C) As the owner, you will be responsible for taking care of the wedding ring until it arrives in the mail. If you do find a wedding ring on your own, it is very rare. (D) It's possible a person is divorced and still wearing a ring because he isn't ready to let go. In that case, he's not a good candidate for a new relationship, anyway.
