Three generations of my family were born in the 20th century

Three generations of my family were born in the 20th century.My grandparents owned comfortable homes with gardens.For my parents,they did not need money from their parents .By the time they had their first child,they also owned a house with a garden.
My generation of professionals ,of course ,is different.We do need degrees,and many of us need help from our parents.We cannot afford a flat,let alone a house ,Why Because our collective parents are making it impossible .As the baby boomer generation –aged 45 to 65 –they are the largest and most powerful political constituency in Britain.And they are using their power to prevent their children from having opportunities equal to their own .They are keeping too much wealth.By the time we inherit ,it will be too late.
Despite population growth,they have constantly failed to increase the supply of available land London is expected to have 700,000 additional households in the next 20 years.Yet in the last year fewer than 25,000 flats were created in the capital.This has been true for decades :the supply of housing has not been allowed to keep pace with demand.Unsurprisingly ,house prices have skyrocketed.
For baby boomers high house prices are a guarantee for the future.That is why cutting inheritance tax is so popular.It is also why people passionately resist new housing in their area.
Of course,it is not all bad.We have grown up in a time of peace,prosperity,and extraordinary technological change .As an educated woman in a developed country,my opportunities are greater than they have ever been.We have reasons to be optimistic about the future .But if the baby boomers are unkind to us –and so for ,they have been – they cannot expect us to be kind to them.

请选择并说出为什么……T0T 都是我一字字打上来的很辛苦啊T0T~

What can we infer from the passage ?
用排除法
A选项错误,因为在原文第二段中My generation of professionals , of course , is different. We do need degrees, and many of us need help from our parents. We cannot afford a flat, let alone a house , （当然,我们这一代人所拥有的“资产”是不同的.我们需要证书、文凭,我们这一代的许多人需要父母的帮助.我们不能自我支付公寓费用,甚至不能支付买房费用.）这句话说明我们这一代年轻人很少拥有house.
B选项正确,在最后一段中For baby boomers high house prices are a guarantee for the future.（对于“婴儿潮”来说,高房价是未来的保证.PS：baby boomers 婴儿潮,这是某个特定的时期的人的总称）其实这个题的原因我觉得可能不好理解,我觉得应该是房价高,导致我们年轻一辈买不了,能听从父母的安排.
C选项错误,在原文第二段有 Because our collective parents are making it impossible . And they are using their power to prevent their children from having opportunities equal to their own . （因为我们的父母使“让子女拥有自己的house”不实现.父母们用他们的权力去阻止他们的后代拥有和他们财富相等的机会.）,所以我们这一代年轻人不能支付买房费用,并不是因为我们lazy,而是因为长辈的原因.
D选项错误,第三段开头Despite population growth, they have constantly failed to increase the supply of available land .这里的they指代the baby boomer generation –aged 45 to 65 ,相当于是我们的grandparents这一辈.
Which word could be used to describe the writer’s attitude towards the housing problem ?
A.uncertain--不确定的
B.doubtful-- 怀疑的
C.satisfied--满意的
D.negative--负面的,反对的
作者对房屋问题的态度是B选项,最后一段As an educated woman in a developed country, my opportunities are greater than they have ever been. We have reasons to be optimistic about the future .（作为一个在发展中国家受到教育的人,我的机会远比我们的长辈更多.我们有理由去乐观看待未来.）,但是在这句话之后有个But if ,说明有别的情况,可能有不确定的情况出现.
嘻嘻,这是我个人观点,仅供参考
再问： 对啊，后面那问我也选B……答案竟然是D…… 我想知道the baby boomers support the big supply of housing 的意思是：the baby boomers（二战后生育高峰期出生的人，文章有注解）控制了房子的供应 还是指 提供很大一部分的房子供应？
再答： support为“支持”的意思，但是针对于这句话，字面上是“婴儿潮时期的人支持了房屋的大量供应”，但我觉得应该理解为“房屋的大量供应是婴儿潮时期的人存在所导致的”，原因是“the baby boomers ”→结果是“the big supply of housing ”
