[单选题]The birth Jacinda Ardern's baby is first and foremost a time of great happiness for Jacinda and her partner,Clarke Gayford.Their daughter is very much a wanted child for these happy parents.But for public in New Zealand and beyon the new arrival in our country's first family also has considerable significance.Ardern becomes only the second serving prime minister in history to give birth.As well,she is not married to her partner.Conventional wisdom may have said that this combination of factors would not have been helpful to a political career at the highest level.Fortunately,that has proved to be wrong.Ardern is a remarkable woman who crashes through glass ceilings with apparent ease.She became Leader of the New Zealand Labour party and of the opposition a mere seven weeks before last September's general election.In that short time,she took her party out of a near death zone of low polling to a highly credible election result,and then through the successful coalition negotiations which re-sulted in her becoming prime minister in October at the age of 37.Ardern's pregnancy came as a surprise to her and Gayford,but they took it in their stride.arrangements were made for Ardern to work until very close to the birth,and then for the deputy prime minister to act in her place while she takes some six weeks maternity leave.After that,Gayford takes over as primary carer for the foreseeable future.For young women,the example Arderm is setting is an affirmation that hey too can expect to have that choice.For young men,Gayford being the full time carer of a baby sends a powerful message that they too can exercise that choice.ony ni New Zealand is known for being a socially progressive country.Arden is its third female prime minister;it has had three female governor generals;and 125 years ago,it became the first countr where women won the right to vote Now it is breaking new ground with a prime minister giving birth and her partner becoming a stay-at-home father.But in the context of New Zealand Is Is evolutionary,not revolutionary Overwhelmingly positive interest across the political spectrum is being taken in the addition to the first What lessons are there in this for our world?In my view,New Zealand is showing that no doors are closed to women,that having a baby while being prime minister can be managed,and that it's acceptable for male partners to be full-time carers.This is very positive role modelling for the empowerment of women and for gender equality.In a world where there are still glass ceilings to be smashed and where many countries continue to have laws,policies,and practices that discriminate against women,the message from New Zealand is one of hope-that women can break through all barriers and do it in their own way as Arden has done I hope that New Zealand will continue to be a leader in the full inclusion of women in all spheres of its society-and i expect it will be
