Question: Question: "Because of the necessary boost it needs, what is the most basic thing that is needed to produce that boost?" Context: "A climbing elevator is a self-ascending elevator with its own propulsion. The propulsion can be done by an electric or a combustion engine. Climbing elevators are used in guyed masts or towers, in order to make easy access to parts of these constructions, such as flight safety lamps for maintenance. An example would be the Moonlight towers in Austin, Texas, where the elevator holds only one person and equipment for maintenance. The Glasgow Tower an observation tower in Glasgow, Scotland also makes use of two climbing elevators." Answer:
Answer: electric or a combustion engine

Question: Question: "Which happened later, the single-grain experiment or the discovery that the amino acid tryptophan aids the well-being of mice?" Context: "In the early 20th century, Carl von Voit and Max Rubner independently measured caloric energy expenditure in different species of animals, applying principles of physics in nutrition. In 1906, Edith G. Willcock and Frederick Hopkins showed that the amino acid tryptophan aids the well-being of mice but it did not assure their growth. In the middle of twelve years of attempts to isolate them, Hopkins said in a 1906 lecture that "unsuspected dietetic factors," other than calories, protein, and minerals, are needed to prevent deficiency diseases. In 1907, Stephen M. Babcock and Edwin B. Hart conducted the single-grain experiment, which took nearly four years to complete." Answer:
Answer: single-grain experiment

Question: Question: "Why isn't Old Dutch the Original language of the Franks?" Context: "Old Low Franconian or Old Dutch is regarded as the primary stage in the development of a separate Dutch language. The "Low" in Old Low Franconian refers to the Frankish spoken in the Low Countries where it was not influenced by the High German consonant shift, as opposed to Central and high Franconian in Germany. The latter would as a consequence evolve with Allemanic into Old High German. At more or less the same time the Ingvaeonic nasal spirant law led to the development of Old Saxon, Old Frisian (Anglo-Frisian) and Old English (Anglo-Saxon). Hardly influenced by either development, Old Dutch remained close to the original language of the Franks, the people that would rule Europe for centuries. The language however, did experienced developments on its own, like final-obstruent devoicing in a very early stage. In fact, by judging from the find at Bergakker, it would seem that the language already experienced this characteristic during the Old Frankish period." Answer:
Answer:
experienced developments on its own
