At the end of the 15th century the Ottoman Empire advanced all over Southeastern Europe, eventually conquering the Byzantine Empire and extending control over the Balkan states. Hungary was the last bastion of the Latin Christian world in the East, and fought to keep its rule over a period of two centuries. After the tragic death of the young king Vladislaus I of Hungary during the Battle of Varna in 1444 against the Ottomans, the Kingdom was placed in the hands of count John Hunyadi, who became Hungary's regent-governor (14461453). Hunyadi was considered one of the most relevant military figures of the 15th century: Pope Pius II awarded him the title of Athleta Christi or Champion of Christ for being the only hope of resisting the Ottomans from advancing to Central and Western Europe.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): In what year did the Battle of Varna take place?
Ah, so.. 1444

Clothing protects against many things that might injure the uncovered human body. Clothes protect people from the elements, including rain, snow, wind, and other weather, as well as from the sun. However, clothing that is too sheer, thin, small, tight, etc., offers less protection. Clothes also reduce risk during activities such as work or sport. Some clothing protects from specific environmental hazards, such as insects, noxious chemicals, weather, weapons, and contact with abrasive substances. Conversely, clothing may protect the environment from the clothing wearer, as with doctors wearing medical scrubs.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Clothing that is sheer will offer more what?
Ah, so.. unanswerable

The presence of pain in an animal cannot be known for certain, but it can be inferred through physical and behavioral reactions. Specialists currently believe that all vertebrates can feel pain, and that certain invertebrates, like the octopus, might too. As for other animals, plants, or other entities, their ability to feel physical pain is at present a question beyond scientific reach, since no mechanism is known by which they could have such a feeling. In particular, there are no known nociceptors in groups such as plants, fungi, and most insects, except for instance in fruit flies.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What do specialists say all invertebrates can feel?
Ah, so..
