Which lines in this excerpt from Macbeth act I, scene 5, show that Lady Macbeth doubts Macbeth’s willpower? [Enter Lady Macbeth, reading a letter.]

LADY MACBETH:
"They met me in the day of success: and I have
learned by the perfectest report, they have more in
them than mortal knowledge. When I burned in desire
to question them further, they made themselves air,
into which they vanished. Whiles I stood rapt in
the wonder of it, came missives from the king, who
all-hailed me 'Thane of Cawdor;' by which title,
before, these weird sisters saluted me, and referred
me to the coming on of time, with 'Hail, king that
shalt be!' This have I thought good to deliver
thee, my dearest partner of greatness, that thou
mightst not lose the dues of rejoicing, by being
ignorant of what greatness is promised thee. Lay it
to thy heart, and farewell."

Glamis thou art, and Cawdor; and shalt be
What thou art promis'd; yet do I fear thy nature;
It is too full o' the milk of human kindness
To catch the nearest way: thou wouldst be great;
Art not without ambition; but without
The illness should attend it. What thou wouldst highly,
That wouldst thou holily; wouldst not play false,
And yet wouldst wrongly win: thou'dst have, great Glamis,
That which cries, "Thus thou must do, if thou have it:
And that which rather thou dost fear to do
Than wishest should be undone." Hie thee hither,
That I may pour my spirits in thine ear;
And chastise with the valor of my tongue
All that impedes thee from the golden round,
Which fate and metaphysical aid doth seem
To have thee crown'd withal.

In just over one hundred years, between 1701 and 1810, 252,500 enslaved africans were brought to barbados—an island that occupies only 166 square miles (making it, today, one of the smallest countries in the world). the english then set out to conquer more sugar islands, starting with jamaica, which they took from spain in 1655. in the same period that the 252,500 africans were brought to barbados, 662,400 africans were taken to jamaica. thus, sugar drove more than 900,000 people into slavery, across the atlantic, to barbados and jamaica—and these were just two of the sugar islands. the english were eagerly filling antigua, nevis, saint kitts, and montserrat with slaves and sugar mills. they took over much of dutch guiana for the same reason. seeing the fortunes being made in sugar, the french started their own scramble to turn the half of the island of hispaniola that they controlled (which is now haiti), as well as martinique, guadeloupe, and french guiana (along the south american coast near dutch guiana), into their own sugar colonies, which were filled with hundreds of thousands more african slaves. by 1753, british ships were taking average of 34,250 slaves from africa every year, and by 1768, that number had reached 53,100. –sugar changed the world, marc aronson and marina budhos how do the authors use historical evidence to support their claim? x(a) they use secondary sources to show how french and english monarchs were indifferent to enslaved people. x(b)they use secondary sources to show that enslaved people often fought for their freedom after arriving in the caribbean. the answer is: (c)they use facts from primary sources to show how countries increased the number of enslaved people to produce more sugar. x(d)they use primary source interviews to show that countries could make more money in trading sugar without using enslaved people.
