Why does lemonade contain artificial flavor while detergents contain real citric acid?

Considering this question one has to distinguish between lemonade and soda (i.e. soft drinks). The basic recipe for homemade lemonade is lemon juice mixed with water and sweetened with sugar. Soda on the other hand is factory-made and, therefore, contains additives such as sweeteners and flavoring agents. But why is that so?
Obviously, sweeteners are used to sweeten the drink. Flavoring agents have a different function. The taste of a drink is limited to the seven basic tastes (sour, sweet etc.) but the possibilities concerning the smell of a drink are way higher. Therefore, flavoring agents are used to alter the smell and consequently the taste of a drink. This, it seems, cannot be done with real flavors. E.g. mixing water with orange juice will cause your drink to taste like orange. With industrial flavoring agents your orange water may smell and taste like chocolate.
Dishwashing liquid is not a beverage. Well, at least you shouldn’t try it. The citric acid in dishwashing liquid is used to soften hard water by binding the metal in hard water. The detergent is then able to produce foam and work more efficiently.
So, the artificial lemon flavor is used for taste while the citric acid helps the detergent to clean the dishes.

Why doesn’t Tarzan have a beard?

Tarzan is a fictional character created by American writer Edgar Rice Burroughs and first appeared in the novel Tarzan of the Apes (1912/1914). He is often described as the archetype of the feral child or the noble savage.
It seems that has never been seen having a beard, so it’s logical to assume he is not able to grow one. The question is why? Maybe he is suffering from alopecia areata, an autoimmune disease causing partial or complete loss of body hair. This idea might be a bit far-fetched but it’s not illogical. Still, it is not the correct answer.
Hoping to find an answer I searched for the e-book of the first Tarzan novel and looked for the word beard. And here’s the thing: Tarzan actually has a beard. In chapter 13 it becomes apparent that he is afraid of becoming an ape. To show that he is a human being he learns to shave and “[a]lmost daily he whetted his keen knife and scraped and whittled at his young beard to eradicate this degrading emblem of apehood.”
Tarzan simply shaves too much.

Do married people live longer or do they only feel that they do?

This strongly depends on whom you are married to. If you’re married to a nagging shrew or to the reincarnation of any late dictator, life can be a long, long song.
But seriously, several studies showed that married people do indeed live longer. Being married and living in harmony causes people to lead a healthier life than singles. While single women tend to become depressed single men become more prone to drinking alcohol and eating unhealthy food.

Is there a synonym for synonym?

Synonyms are words with the same or at least a similar meaning which can occur in any parts of speech, i.e. verbs, adjectives etc. The only condition is that both words belong to the same parts of speech. An example for synonymous verbs would be buy and purchase.
There is indeed a synonym for synonym. It most likely has vanished in modern day English but it exists nonetheless. The Latin word poecilonym is defined in the Oxford English Dictionary as “any of several names for the same thing”. See, there is a synonym for synonym.
