Question

a successful modern dancer is writing an autobiography. read the piece of information in each row, then select the section where it fits best.
i come from a long line of football enthusiasts. the assumption held by my older relatives that all of their male offspring would enjoy and play the game had never before been questioned.
a knee injury kept me from participating in any summer intensive or apprenticeship programs that year. i worried that the lost time would derail my career before it even began.
i was at a point in my career when i wanted to explore internal feelings and veer away from showiness. it was then that i met amber, a choreographer who encouraged her dancers to close their eyes and move from within.
when i was a young boy, a babysitter was switching television channels when she settled on a public television station that was airing a modern dance piece performed by a local troupe. i was transfixed.

Explanation:

• The first row: The family's assumption about male offspring (football) is an obstacle for the dancer (as he's a modern dancer). So it fits "Challenges & obstacles".
• The second row: Knee injury preventing participation in programs and worrying about career derailment is clearly a challenge/obstacle.
• The third row: Meeting Amber (a collaborator/choreographer) when the dancer wanted to explore a new aspect (internal feelings) makes it fit "Colleagues & collaborators".
• The fourth row: Being transfixed by a modern dance piece on TV as a young boy shows what inspired the dancer. So it fits "Inspiration".

Answer:

• First row: Challenges & obstacles
• Second row: Challenges & obstacles
• Third row: Colleagues & collaborators
• Fourth row: Inspiration
