A shopping mall was recently built near Mary's neighborhood. Soon Mary began to notice fewer birds at her bird feeder. What can Mary infer?

mary can infer that since the new shopping mall is now there the builder's of this shopping mall must have chopped down the trees the birds were living in to implement the new shopping mall

mary can infer that there are fewer birds now then before because the birds homes (trees) were chopped of by the builders because they needed to build a new mall
