Read the passage. The official class naturally disliked to see people leave the country and were disposed to sneer at almost everything American. Being well educated at the university and holding their offices for life, they were looked up to with great respect by the common country-people. NO wonder, therefore, that to the official class many things in America seemed bizarre. Just think, a railsplitter being president and a tailor vice-president! Besides, was not almost everybody in America carrying revolvers, and quick on the trigger on slight provocation? Was not justice administered by mobs or vigilance committees? In addition to that, there was negro slavery and so much humbug—"American humbug!” Why should any one go to a country like that?
Some had gone, however, following the Sloopers of '25 from 1836 on, but they were mostly tenants or very poor farmers who had barely scraped up enough to pay the passage on sailships and canal boats as far as Chicago or Milwaukee. Of some of the few educated persons leaving it was said they were no longer safe at home and that for them America was a safer and more suitable place. Letters were coming back from the poor emigrants, telling how much land they had acquired for little or nothing, how much stock they had and how they fared on pork, eggs, and white bread every day, instead of in Norway (as they used to say) "one day on soup and herring and the next day on herring and soup,” or "one day mush and milk and the next day milk and mush.”

I believe it's A

Explanation:

"but they were mostly tenants or very poor farmers who had barely scraped up enough to pay the passage on sailships and canal boats as far as Chicago or Milwaukee. Of some of the few educated persons leaving it was said they were no longer safe at home and that for them America was a safer and more suitable place."

the bar kochba rebellion (132-135) against the roman empire, also known as the second jewish-roman war, was the second major jewish revolt in judea and the last of the great jewish-roman wars.

after the first jewish-roman war of the years 66-73, the roman authorities took measures to crush any new attempt of rebellion in judea. his political situation was modified and instead of a prefect a governor of praetorian rank was appointed, and in the ruins of jerusalem the seat of a complete roman legion, the legio x fretensis was established.

the political and religious direction of the jewish people was left in the hands of the sanhedrin, with initial headquarters in yavne.

the direct causes of the rebellion vary according to the source. the roman historian dio cassius (155-229) attributes the revolt to the decision of hadrian to found in the place of jerusalem a roman city called aelia capitolina (aelia by its own name and capitolina in honor of the roman god jupiter). on the other hand, the jewish sources, while recognizing this resolution as true, assign higher priority to the decrees dictated by hadrian that forbade the brit milah (circumcision), the respect of the sabbath and the laws of purity in the family.

hadrian's intention was to "civilize" and incorporate the jews once and for all into the greco-roman culture. for greek and roman culture, circumcision was an intolerable mutilation.

the jewish tradition tells in the midrash tanjuma a meeting between rabbi akiva and the governor turnus rufus, where he asked for an explanation about the circumcision.

an additional legion, the legio vi ferrata, moved to the province to maintain order, and work began in the year 131 after the governor of judea, turnus rufus performed the founding ceremony of aelia capitolina. a roman coin with the inscription aelia capitolina was struck in the year 132.

the tannaim rabbi akiva, who without being named nasi directed the sanhedrin, convinced the other members to support the imminent rebellion.

the jewish leaders carefully planned the second rebellion to avoid the numerous errors that had been committed in the first one. in the year 132 the rebellion led by bar kochba quickly expanded from modiim throughout the country, defeating the x roman legion based in jerusalem and destroying the xxii roman legion that had come from egypt.
