Question

read the passage. there are several questions about this passage. from settled in the wild 1 it is a rainy morning, the first week of may, good weather to plant nasturtiums. i sit on the porch steps with rubber boots on, a baseball cap, and a slicker, holding the packages of seeds i bought at the feed store in town yesterday. the rain is steady and cold, the light is steel gray, and the yard is patchy and wet. but the pictures on the packages vibrate with color. nothing looks as good as these nasturtium flowers right now: deep red, eye - jolting orange, electric yellow. 2 absentmindedly, i begin to recite william wordsworth’s \i wandered lonely as a cloud\ to myself. i have known the poem by heart ever since my father taught it to me when i was a child: for oft, when on my couch i lie in vacant or in pensive mood, they flash upon the inward eye which is the bliss of solitude; and then my heart with pleasure fills, and dances with the daffodils. 3 wordsworth’s inner eye saw daffodils, i say the poem and see hummingbirds. the nasturtiums are for them, and planting the flowers is my gesture of faith that they will come back to my yard once more. as i rip open the packages and push the seeds into the dirt, i know that these tiny bright - colored nectar - drinking birds, each of whom weighs only a few grams—about the weight of four or five of these seeds—have already whirred in erratic flocks across five hundred miles of open water, running the gulf of mexico in a twenty - six - hour feat. 4 hummers do exactly what physiologists once insisted they could not do. a bird that weighs so little, they argued, cannot go from the yucatán to the which idea about hummingbirds is least explained in the passage? 1. what the birds do to \survive cool maine nights\ (paragraph 7) 2. what creates colors of \iridescent reds and greens\ in the mature bird (paragraph 10) 3. why only a \few fossilized bones\ of the birds have been found (paragraph 11) 4. why some bird \species were lost\ before being named (paragraph 12)

Explanation:

1. Paragraph 7 likely gives some details on how humming - birds survive cool Maine nights.
2. Paragraph 10 probably explains what creates the colors of iridescent reds and greens in the mature bird.
3. Paragraph 11 gives no real explanation as to why only a few fossilized bones of the birds have been found. It just states the fact.
4. Paragraph 12 may give some reasons for why some bird species were lost before being named.

Answer:

1. why only a "few fossilized bones" of the birds have been found (Paragraph 11)
