Answer 1

-------Quantitative research is the systematic scientific investigation of quantitative properties and phenomena and their relationships. The objective of quantitative research is to develop and employ mathematical models, theories and/or hypotheses pertaining to natural phenomena. The process of measurement is central to quantitative research because it provides the fundamental connection between empirical observation and mathematical expression of quantitative relationships.

-------The gram (often gramme in British English), (Greek/Latin root grámma); symbol g, is a unit of mass.

Originally defined as "the absolute weight of a volume of pure water equal to the cube of the hundredth part of a metre, and at the temperature of melting ice"[1] (later 4 °C), a gram is now defined as one one-thousandth of the SI base unit, the kilogram, or 1×10-3 kg, which itself is defined as being equal to the mass of a physical prototype preserved by the International Bureau of Weights and Measures.

---------The litre or liter (see spelling differences) is a unit of volume. There are two official symbols: the Latin letter L in lower (l) and upper case (L). The litre appears in several versions of the metric system; although not an SI unit, it is accepted for use with the SI. The international unit of volume is the cubic metre (m3). One litre is equal to 0.001 cubic metre and is denoted as 1 cubic decimetre (dm3).

The word "litre" is derived from an older French unit, the litron, whose name came from Greek via Latin. The original metric system used the litre as a base unit.

--------In science a theory is a testable model of the manner of interaction of a set of natural phenomena, capable of predicting future occurrences or observations of the same kind, and capable of being tested through experiment or otherwise verified through empirical observation. For the scientist, "theory" is not in any way an antonym of "fact". For example, it is a fact that an apple dropped on earth has been observed to fall towards the center of the planet, and the theories commonly used to describe and explain this behavior are Newton's theory of universal gravitation (see also gravitation), and the general theory of relativity.

In common usage, the word theory is often used to signify a conjecture, an opinion, a speculation, or a hypothesis. In this usage, a theory is not necessarily based on facts; in other words, it is not required to be consistent with true descriptions of reality. True descriptions of reality are more reflectively understood as statements which would be true independently of what people think about them.

-------The metre or meter[1] is a measure of length. It is the basic unit of length in the metric system and in the International System of Units (SI), used around the world for general and scientific purposes. Historically, the metre was defined by the French Academy of Sciences as the length between two marks on a platinum-iridium bar, which was designed to represent 1⁄10,000,000 of the distance from the equator to the north pole through Paris. Today, it is defined by the International Bureau of Weights and Measures as the distance travelled by light in absolute vacuum in 1⁄299,792,458 of a second.

The symbol for metre is m (never capital M). Decimal multiples and submultiples of the metre, such as kilometre (1000 metres) and centimetre (1⁄100 metre), are indicated by adding SI prefixes to metre (see table below).

The spelling of the word recommended by the General Conference on Weights and Measures is "metre".[2] However, many scholars, manufacturers and traders in USA prefer using the American English spelling "meter", also officially endorsed by the US Federal Government.[3]

-------A conclusion is a proposition, which is arrived at after the consideration of evidence, arguments or premises

In both formal and informal logic, a main contention is a thought which is capable of being either true or false and is usually the most controversial proposition being argued for. In reasoning, a main contention is represented by the top of an argument map, with all supporting and objecting premises which bear upon it placed underneath. A main contention is given a different order and is placed at the start of an argument and not at the end.
