4 white lettering and symbols painted on the surface of the roadway are used to provide valuable information to road users in the form of supplement signs.

Explanation:

On the first hand, drivers learn a certain amount of signs and codes that provide them information about the roads they use, to have as much information from them. This is crucial because they have to get access to all sources of information to live the best experience they can on the road. On the second hand, the federal highway administration of the U.S. has determined a general language all drivers are meant to know to face all the possible outcomes that a trip in the road can provide.

Now, 4 white lettering and symbols painted on the surface of the roadway give real-time information of the road and communicate to the driver everything he has to know to have a safe trip and avoid any sort of accident.

answer:   migrations were important in the neolithic period. "two major migrations passing through southeastern europe were confirmed by the means of archaeo-genetic studies."

the first migration was the early neolithic period -- 6,000 before common era (bce) -- when the first farmers, from anatolia -- asia minor -- spread through europe. the second migration occurred during the early bronze age (3,000-2,500 bce) when the so-called "steppe population," from the eurasian steppe, replaced much of northern europe's previous population.

the first farmers of northern and western europe passed through southeastern europe with limited hunter-gatherer genetic admixture, which occurs when two or more previously isolated populations begin interbreeding. however, some groups that remained mixed extensively -- without the male-biased, hunter-gatherer admixture that prevailed later in the north and west, according to latest discoveries. southeastern europe continued to be a nexus between east and west, with intermittent genetic contact with the steppe people up to 2,000 years before the migrations that replaced much of northern europe's population.

"in some places, hunter-gatherers and incoming farmers seem to have mixed very quickly," says iain mathieson, a geneticist at the university of pennsylvania, who was first author of the paper. "but, mostly, the two groups remained isolated, at least for the first few hundred years. these hunter-gatherers had been living there for thousands of years, and it must have been quite a shock to have these new people show up -- with a completely different lifestyle and appearance."
