Although asthma is a chronic obstructive condition, it is not considered as a part of chronic obstructive pulmonary disease as this term refers specifically to combinations of disease that are irreversible such as bronchiectasis, chronic bronchitis, and emphysema. Unlike these diseases, the airway obstruction in asthma is usually reversible; however, if left untreated, the chronic inflammation from asthma can lead the lungs to become irreversibly obstructed due to airway remodeling. In contrast to emphysema, asthma affects the bronchi, not the alveoli.

What are examples of chronic obstructive pulmonary disease?
Answer: bronchiectasis, chronic bronchitis, and emphysema

Problem: Several Germanic tribes celebrated the returning of the daylight. A predominant deity was during this jubilee driven around in a noisy procession on a ship on wheels. The winter would be driven out, to make sure that fertility could return in spring. A central figure was possibly the fertility goddess Nerthus.

Aboard the ship would the marriage of a man and woman be consummated as a fertility ritual.
How was the ship carrying a predominant deity moved around during the jubilee?
The answer is the following: on wheels

In Czech, nouns and adjectives are declined into one of seven grammatical cases. Nouns are inflected to indicate their use in a sentence. A nominativeaccusative language, Czech marks subject nouns with nominative case and object nouns with accusative case. The genitive case marks possessive nouns and some types of movement. The remaining cases (instrumental, locative, vocative and dative) indicate semantic relationships, such as secondary objects, movement or position (dative case) and accompaniment (instrumental case). An adjective's case agrees with that of the noun it describes. When Czech children learn their language's declension patterns, the cases are referred to by number:
