Problem: Neutering reduces problems caused by hypersexuality, especially in male dogs. Spayed female dogs are less likely to develop some forms of cancer, affecting mammary glands, ovaries, and other reproductive organs. However, neutering increases the risk of urinary incontinence in female dogs, and prostate cancer in males, as well as osteosarcoma, hemangiosarcoma, cruciate ligament rupture, obesity, and diabetes mellitus in either sex.
What is increased in male dogs with neutering?
The answer is the following: prostate cancer

Problem: Asthma is characterized by recurrent episodes of wheezing, shortness of breath, chest tightness, and coughing. Sputum may be produced from the lung by coughing but is often hard to bring up. During recovery from an attack, it may appear pus-like due to high levels of white blood cells called eosinophils. Symptoms are usually worse at night and in the early morning or in response to exercise or cold air. Some people with asthma rarely experience symptoms, usually in response to triggers, whereas others may have marked and persistent symptoms.
What are the characteristics of asthma?
The answer is the following: recurrent episodes of wheezing, shortness of breath, chest tightness, and coughing

Problem: The term middle east as a noun and adjective was common in the 19th century in nearly every context except diplomacy and archaeology. An uncountable number of places appear to have had their middle easts from gardens to regions, including the United States. The innovation of the term "Near East" to mean the holdings of the Ottoman Empire as early as the Crimean War had left a geographical gap. The East Indies, or "Far East," derived ultimately from Ptolemy's "India Beyond the Ganges." The Ottoman Empire ended at the eastern border of Iraq. "India This Side of the Ganges" and Iran had been omitted. The archaeologists counted Iran as "the Near East" because Old Persian cuneiform had been found there. This usage did not sit well with the diplomats; India was left in an equivocal state. They needed a regional term.
Where did the "Far East" derive from? 
The answer is the following:
Ptolemy's "India Beyond the Ganges."
