What conclusion can you draw from the statement, “the challenge is to scale up these technologies to deliver power in industrial quantities…”? these technologies still need to be improved to be safe for the environment. these technologies are cheaper than traditional energy sources, such as oil. people should immediately switch to new technologies, such as wind turbines. these technologies are not yet available in amounts we need.

One element of lyric poetry is personal reflection. which lines in this poem most clearly illustrate that element? i wandered lonely as a cloudby william wordsworthi wandered lonely as a cloudthat floats on high o'er vales and hills,when all at once i saw a crowd,a host, of golden daffodils; beside the lake, beneath the trees,fluttering and dancing in the breeze.continuous as the stars that shineand twinkle on the milky way.they stretched in never-ending linealong the margin of a bay: ten thousand saw i at a glance,tossing their heads in sprightly dance.the waves beside them danced; but theyout-did the sparkling waves in glee: a poet could not but be gay.in such a jocund company: i gazed and gazed—but little thoughtwhat wealth the show to me had brought: for oft, when on my couch i liein vacant or in pensive mood,they flash upon that inward eyewhich is the bliss of solitude; and then my heart with pleasure fills,and dances with the daffodils.
