Before Charlemagne, research was primarily conducted by scholars and scribes in monasteries and other centers of learning. The focus of research was largely on religious texts, philosophy, and classical literature. The methods of research were primarily based on reading and interpreting existing texts, as well as copying and preserving important works. There was also some limited experimentation and observation in fields such as medicine and astronomy, but overall, research was not as systematic or widespread as it would become during the Carolingian Renaissance under Charlemagne's patronage. **

Before Charlemagne, research was primarily conducted by scholars in monasteries and other religious institutions. These scholars focused on studying religious texts, philosophy, and classical literature. Research was often limited to the resources available within these institutions, such as manuscripts and scrolls. There was also a strong emphasis on preserving and copying existing knowledge rather than generating new ideas or discoveries. **

The weather forecast changes until shortly before the weather because weather is a complex and dynamic system influenced by various factors such as temperature, pressure, humidity, and wind patterns. These factors can interact in unpredictable ways, leading to changes in the forecast as new data becomes available. Additionally, advancements in technology and data collection allow meteorologists to continuously update and refine their forecasts as they receive more accurate and detailed information about the current atmospheric conditions. As a result, the forecast can change as the time approaches, reflecting the most up-to-date understanding of the weather patterns. **

Systematic observation in field research involves the structured and planned collection of data through direct observation of a specific phenomenon, often using predetermined categories or criteria. On the other hand, participant observation involves the researcher immersing themselves in the social setting being studied, actively participating in the activities and interactions of the group being observed. While systematic observation allows for a more objective and standardized approach to data collection, participant observation provides a deeper understanding of the social context and dynamics by experiencing it firsthand. Ultimately, the main distinction lies in the level of involvement and interaction between the researcher and the subjects of the study. **

Systematic observation in field research involves the structured and predetermined collection of data based on specific variables or behaviors of interest. Researchers use predefined criteria to guide their observations and ensure consistency in data collection. On the other hand, participatory observation involves the researcher immersing themselves in the social setting being studied, actively participating in the activities of the group being observed. This approach allows the researcher to gain a deeper understanding of the context and culture of the group, but may be more subjective and less structured compared to systematic observation. **

It is not necessary to put a space before numbers in most cases. However, in certain style guides or languages, such as French, it is common to put a space before numbers. Ultimately, it depends on the specific style guide or language conventions being followed. In general, it is best to be consistent in your use of spacing before numbers to maintain clarity and readability in your writing. **

Conducting internet research before an exam can be considered cheating if the exam rules explicitly state that no external resources are allowed. It is important to follow the guidelines set by the instructor or exam proctor to maintain academic integrity. However, if the exam permits the use of external resources or if internet research is allowed, then it would not be considered cheating. It is always best to clarify any doubts with the instructor beforehand to avoid any misunderstandings. **
