[Q]: The vast majority of states in the United States employ a system of recording legal instruments (otherwise known as deeds registration) that affect the title of real estate as the exclusive means for publicly documenting land titles and interests. This system differs significantly from land registration systems, such as the Torrens system that have been adopted in a few states. The principal difference is that the recording system does not determine who owns the title or interest involved, which is ultimately determined through litigation in the courts. The system provides a framework for determining who the law will protect in relation to those titles and interests when a dispute arises.
[A]: the fundamental purpose of recording instruments that affect real property is to

[Q]: Gutenberg in 1439 was the first European to use movable type. Among his many contributions to printing are: the invention of a process for mass-producing movable type; the use of oil-based ink for printing books; adjustable molds; mechanical movable type; and the use of a wooden printing press similar to the agricultural screw presses of the period. His truly epochal invention was the combination of these elements into a practical system that allowed the mass production of printed books and was economically viable for printers and readers alike. Gutenberg's method for making type is traditionally considered to have included a type metal alloy and a hand mould for casting type. The alloy was a mixture of lead, tin, and antimony that melted at a relatively low temperature for faster and more economical casting, cast well, and created a durable type.
[A]: who developed the first printing press in 1430

[Q]: In some fields, quantitative research may begin with a research question (e.g., 'Does listening to vocal music during the learning of a word list have an effect on later memory for these words?') which is tested through experimentation. Usually, a researcher has a certain theory regarding the topic under investigation. Based on this theory, statements or hypotheses will be proposed (e.g., 'Listening to vocal voice has a negative effect on learning a word list.'). From these hypotheses, predictions about specific events are derived (e.g., 'People who study a word list while listening to vocal music will remember fewer words on a later memory test than people who study a word list in silence.'). These predictions can then be tested with a suitable experiment. Depending on the outcomes of the experiment, the theory on which the hypotheses and predictions were based will be supported or not, or may need to be modified and then subjected to further testing.
[A]:
when should a hypothesis be developed by the researcher during the research process
