The first case, where I quote from, is "oldest child is a boy and oldest child is born on Tuesday". The 14 possibilities for the youngest child are then ennumerated, which include a second boy born on Tuesday.
Then, he consider the set: NOT(oldest child=boy AND oldest child=born on Tuesday). The youngest child then has to be, since at least one of the children is a boy born on Tuesday. Then, because we're specifically considering the subcase that excludes an oldest child who's a boy born on a Tuesday, there are 13 possibilities for the oldest: a girl born on any day, or a boy born on any day besides Tuesday.
There is no only implied or forgotten in the original question.
If the older child is a boy born on Tuesday, there are 14 equally likely possibilities for the sex and birth day of his younger sibling: a girl born on any of the seven days of the week or a boy born on any of the seven days of the week.
One of those 14 possibilities is another boy born on Tuesday. The exclusion mentioned in the next paragraph is to avoid counting that case twice.
More importantly, I don't think you're giving your fellow Australians enough credit. Essentially, you're saying that, on the whole, none of you can be fucked to skim a Wikipedia article before heading to the polls. I'm sorry you feel that your country can only handle what the nice, caring overlords decide to spoon-feed them. Seriously, give me a break.
Maybe instead of bitching about the government failing to inform you that this was a perfectly legal possibility, you could take this opportunity to try, in your own way, to help educate other people. Phone your local schools and ask about the civics curriculum. Tell them you think this is a problem and make suggestions to fix it. Take ownership instead of saying, "No one did my job for me, how unfair."
In short, if you thought that at the last election you were voting for the prime minister then you are, as per the meme, doin it rong.
The only other similar opening near the volcano was found in 2007, when Glen Cushing, a scientist with the U.S. Geological Survey, published a research paper on the surface anomalies.
The opening is estimated to be 620 feet by 520 feet and the hole to be at least 380 feet deep."

"We also are encouraging Canada to provide its customs authorities with the authority to seize pirated and counterfeit products," McCoy said
So it's not enough that you expect Canada to bend over on command re: copyright law. More than that, you'd like our government to ignore the Charter of Rights and Freedoms (article 8) for your convenience? Dear Mr USTR: you can kiss my infringing, frost-bitten ass.
Would they be just the thing for people to use to infringe with impunity and anonymously bypass the chances of running foul of the Digital Economy Act?
Not necessarily... there are ways of having public WiFi without letting everyone use it anonymously. Singapore has pretty much full coverage, but to use the public hotspots you need to create an account, and your account has to be tied to a cell phone number (with a confirmation text that you have to respond to). Now I'm sure a clever person could find ways around the system, but it's still just another barrier. I wouldn't be suprised if London did something similar- from TFA:
Not only will this allow people walking the streets to access the wi-fi connections, but it will also allow local homes access too. This will most likely require some sort of payment, however, but may be significantly cheaper than current packages offered through internet service providers.
If it's going to be payment system, then there has to be some sort of personal account that people can create (and the ability to individually monitor people can then be spun as an added bonus).
