付箋の貼ってるところのadults bornのところがよくわかりません。born はbe動詞と一緒に使いませんか?

やや難 例題 次の文章はある報告書の一部である。 この文章と図を読み、問1~4 ] に入れるのに最も適当なものを,それぞれ下の①~④のうち から一つずつ選べ。 Magnet and Sticky: A Study on State-to-State Migration in the US (1) Some people live their whole lives near their places of birth, while V-F Q Vi others move elsewhere. A study conducted by the Pew Research Center (looked into the state-to-state moving patterns of Americans.) The study zens examined each state (to determine how many of their ad have moved there from othe these residents) are called "ma es of study also s both S investigated what percent of adults born in each state are still living there.) States high in these numbers are called "sticky" states. The study were magnet and sticky, while others were found that some states neither. There were also states that were only magnet or only sticky. (2) Figures 1 and 2 show how selected states rank 6n magnet and sticky scales respectively. Florida is a good example of a state that ranks high on both) Seventy percent of its current adult population was born in another state; at the same time, 66% of adults born in Florida are still living there. (On the other hand, West Virginia is neither magnet (only 27%) nor particularly sticky (49%). (In other words, it has few newcomers, and relatively few West Virginians stay there. Michigan is a typical example of a state which is highly sticky, but very low magnet, (In contrast, Alaska, which ranks near the top of the magnet scale, is the Vi least sticky of all states. S V VA (3) Three other extreme examples also appear in Figures 1 and 2. The first is Nevada, where the high proportion of adult residents born out of Svi CL V+ 9 V₁ state makes this state America's top magnet. New York is at the opposite end of the magnet scale even though it is attractive to immigrants from other nations The third extreme example is Texas, át the opposite end of the sticky scale from Alaska. Although it is a fairly weak magnet, Texas SV₁ is the nation's stickiest state.
