If a source appears credible based on the bibliographical info, what you should do next is C. evaluate the content of the source.
First of all, you need to read or watch the actual source so as to get an idea of what information you can use out of it. So, the creation of a research plan, organization of the data, and writing an outline happens after you evaluate the content for the data you may need.

DUKE. Say it, Othello.
OTHELLO. Her father loved me, oft invited me,
Still question'd me the story of my life
From year to year, the battles, sieges, fortunes,
That I have pass'd.
I ran it through, even from my boyish days
To the very moment that he bade me tell it:
Wherein I spake of most disastrous chances,
Of moving accidents by flood and field,
Of hair-breadth 'scapes i' the imminent deadly breach,
Of being taken by the insolent foe
And sold to slavery, of my redemption thence
And portance in my travels' history;
Wherein of antres vast and deserts idle,
Rough quarries, rocks, and hills whose heads touch heaven,
It was my hint to speak—such was the process—
And of the Cannibals that each other eat,
The Anthropophagi, and men whose heads
Do grow beneath their shoulders. This to hear
Would Desdemona seriously incline;
But still the house affairs would draw her thence,
Which ever as she could with haste dispatch,
She'ld come again, and with a greedy ear
Devour up my discourse;</span>

The answer is: The land was cold, desolate, and dangerous, and the Pilgrims could not rely on the ship or their friends in Europe
