proper question: What else does an agency have a relationship with under the civil disobedience definition?
disfluent question: What else does an agency have a relationship with under the constitutional impasse I mean civil disobedience definition?
context: Civil disobedience is usually defined as pertaining to a citizen's relation to the state and its laws, as distinguished from a constitutional impasse in which two public agencies, especially two equally sovereign branches of government, conflict. For instance, if the head of government of a country were to refuse to enforce a decision of that country's highest court, it would not be civil disobedience, since the head of government would be acting in her or his capacity as public official rather than private citizen.

disfluent question: How was the or rather where was the less popular trading center for the Ottoman empire?
context: With Istanbul as its capital and control of lands around the Mediterranean basin, the Ottoman Empire was at the center of interactions between the Eastern and Western worlds for six centuries. Following a long period of military setbacks against European powers, the Ottoman Empire gradually declined into the late nineteenth century. The empire allied with Germany in the early 20th century, with the imperial ambition of recovering its lost territories, but it dissolved in the aftermath of World War I, leading to the emergence of the new state of Turkey in the Ottoman Anatolian heartland, as well as the creation of modern Balkan and Middle Eastern states, thus ending Turkish colonial ambitions.

disfluent question: What is not used by any form of organism um no invertebrate?
context: Pattern recognition receptors are proteins used by nearly all organisms to identify molecules associated with pathogens. Antimicrobial peptides called defensins are an evolutionarily conserved component of the innate immune response found in all animals and plants, and represent the main form of invertebrate systemic immunity. The complement system and phagocytic cells are also used by most forms of invertebrate life. Ribonucleases and the RNA interference pathway are conserved across all eukaryotes, and are thought to play a role in the immune response to viruses.
