Answer:
A "The spring of 1998 was the Halley’s Comet of desert wildflower years." (lines 1–2)
Explanation:
This is the excerpt from Barbara Kingsolver's scientific essey "Called Out". It describes events in the spring of 1998 and gives insight on magnificent and complex life cycle of desert plants.
The given sentence provides description of the highway medians suggesting that there were unusually many flowers, rarely seen before.
That provides evidence to answer A. which claims that that spring was the Halley's Comet of desert wildflower years. Halley's Comet is a rare phenomenon that happens only once every 76 years, so by making this comparison, the author claims that what happened that spring was a true botanical rarity.

<span>B. We were walking by the lake when we heard a siren.

<span>Macbeth is both excited and fearful after hearing the witches' prediction about his future because D. the witches told Macbeth that he would be kind, and he is worried about his role in making the prediction come true. Eventually, it turned out the witches were right, as Macbeth did become king, but only after killing the incumbent king Duncan. Afterwards, his wife and accomplice went mad with guilt and committed suicide, and Macbeth was also killed for his crimes in the end.</span>
