Answer:1

You can use any of the following methods to choose a particular element from the matched set:

// show the first .item only  
$('.item:first').show();
$('.item').first().show();

// show the last .item only
$('.item:last').show();
$('.item').last().show();

// show the second .item only
$('.item:eq(1)').show();
$('.item').eq(1).show();

Note that eq takes a parameter which is the index of the element you want to target.
