In theory, the stadtholders were freely appointed by and subordinate to the states of each province. However, in practice the princes of Orange of the House of Orange-Nassau, beginning with William the Silent, were always chosen as stadtholders of most of the provinces. Zeeland and usually Utrecht had the same stadtholder as Holland.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who were always chosen as stadtholders of most of the provinces?
Ah, so.. the princes of Orange of the House of Orange-Nassau, beginning with William the Silent

Less than 1% of all species that have been described have been studied beyond simply noting their existence. The vast majority of Earth's species are microbial. Contemporary biodiversity physics is "firmly fixated on the visible [macroscopic] world". For example, microbial life is metabolically and environmentally more diverse than multicellular life (see e.g., extremophile). "On the tree of life, based on analyses of small-subunit ribosomal RNA, visible life consists of barely noticeable twigs. The inverse relationship of size and population recurs higher on the evolutionary ladder"to a first approximation, all multicellular species on Earth are insects". Insect extinction rates are highsupporting the Holocene extinction hypothesis.

Ah, so.. Contemporary biodiversity physics

As aircraft started to be used against ground targets on the battlefield, the AA guns could not be traversed quickly enough at close targets and, being relatively few, were not always in the right place (and were often unpopular with other troops), so changed positions frequently. Soon the forces were adding various machine-gun based weapons mounted on poles. These short-range weapons proved more deadly, and the "Red Baron" is believed to have been shot down by an anti-aircraft Vickers machine gun. When the war ended, it was clear that the increasing capabilities of aircraft would require better means of acquiring targets and aiming at them. Nevertheless, a pattern had been set: anti-aircraft weapons would be based around heavy weapons attacking high-altitude targets and lighter weapons for use when they came to lower altitudes.

Ah, so..
AA guns
