Barney and marshall have been participating in outdoor activities. barney has been hiking and doing tai-chi alone in the park. marshall has been playing 3-on-3 basketball and soccer. which long term benefit will marshall experience, but barney will most likely not?
better overall health
better body composition
better peer relationships
better mental health

The answer is "Better peer relationships".

“Peer acceptance speaks to societal position or prominence inside a substantial gathering, while friendships speak to connections dependent on shared regard, thankfulness, and loving." Both companion connections and fellowships turn out to be progressively imperative as kids develop into youth. Encountering positive peer relationships and fellowships add to positive mental self view, social skill and scholarly accomplishment, among different results, and may go about as a cushion against the negative effect of family inconveniences. Youngsters who think that its hard to grow such connections will probably be forceful, lonely and discouraged.
