Read the excerpt from Immigrant Kids by Russell Freedman. The writer Angelo Pellegrini has recalled his own family’s detention at Ellis Island:

We lived there for three days – Mother and we five children, the youngest of whom was three years old. Because of the rigorous physical examination that we had to submit to, particularly of the eyes, there was this terrible anxiety that one of us might be rejected. And if one of us was, what would the rest of the family do? My sister was indeed momentarily rejected; she had been so ill and had cried so much that her eyes were absolutely bloodshot, and Mother was told, "Well, we can’t let her in.” But fortunately, Mother was an indomitable spirit and finally made them understand that if her child had a few hours’ rest and a little bit to eat she would be all right. In the end we did get through.
Most immigrants passed through Ellis Island in about one day. Carrying all their worldly possessions, they left the examination hall and waited on the dock for the ferry that would take them to Manhattan, a mile away. Some of them still faced long journeys overland before they reached their final destination. Others would head directly for the teeming immigrant neighborhoods of New York City.

Which line from the excerpt is an example of a quotation?

Some of them still faced long journeys overland . . .

"Well, we can't let her in."

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."
