the Muslim advances in science and medicine spreading across Europe was on effect of the Crusades is true
The question is extremely vague. “Ancient” covers a large period of time that had varied technologies. “Communication” is also a very vague term. That being said, I will attempt to give an answer.
I am assuming that you are asking about human communication. One of the things that distinguishes humans from animals is speech. Probably the most ancient means of communication was speech. Hand gestures, body language, and facial expressions are also a means of communication. Dance and music were also very ancient means of communication.
Messengers with verbal messages, signal fires, totems, banners, cave art, etc. were ancient means of communication that predate history.
Proto alphabets and pictographs were used as early as 60,000 years ago. Such script was found on egg shells dating back that far and found in southwestern Africa.
Genuine writing began as early as 5,000 years BC with the Vinca script (although this is disputed). It is undisputed that cuneiform script was in use in what is now Iraq about 3,000 BC. This early writing was typically impressed on clay tablets and allowed to dry. Small tablets could be transported between distant locations. Some script was also present on pottery. Rudimentary codes were used for distant communication with signal fires. Drums could be heard at great distances and were also used to communicate. Once paper was invented, things really took off, literally. Messenger pigeons were used as early as 1150 in Baghdad and also later by Genghis Khan. This ancient means of aerial communication was still in wide use in World War I.
More common were couriers on horseback that would take written messages quickly between people at distances. In ancient Persia (Iran) they had messengers, called angros that would carry messages in stations that had a day's ride distance along the royal road. The riders were exclusively in the service of government. A message could be transported from Susa (south western Iran) to Sardis (western Turkey), a distance of 1,677 miles in just seven days. The same journey took ninety days on foot. This type of system was later used by the Romans. Messages were also transported by boats and ships.
Even ancient communication could be relatively fast.
Answer:
Letter C is the correct answer.
Explanation:
No Child Left Behind (or NCLB) was a law for K-12 Education in the U.S. between 2002 and 2015 (it was replaced by Every Student Succeeds Act that year) and the main issue was how children were learning at school.
Options A, B, and D are related to the academic status of the professor, since A talks about tests taken by teachers; letter B refers to state qualifications in the area teachers have in charge; letter D also talks about how professors can prove they are able to teach their subjects: all these options are strictly related to how children can learn and how exams and certifications can help teachers in this task. On the other hand, Letter C does not relate directly to students' performance in the classroom, and that is why this is the correct answer.
Answer:
True, every relationship has problems
Answer:
Option E is not correct.
Explanation:
The time of the day will have a direct impact on the results of this survey.
If the survey is conducted at midnight, the number of cars may not even reach 25. A high school usually is more concurred between class hours, therefore, is recommendable to conduct the survey between those hours. Thus, the statement is NOT correct.
