A blockade is where a region's goods are blocked from being able to enter or leave, a bit like a siege, so I don't think it fits the "defensive" part of the clue here.
Let me explain another way. Have a look at this list of blockades in history - there are about 60 listed there. The interesting thing is that not one of them was defensive. They were all hostile acts aimed at a defending country or region, which is why "blockade" would not be an accurate answer to the clue Defensive barrier.
I agree...we blockade to stop arms from reaching the enemy....it was very defensive during the Cuban Missile Crisis! We were keeping nukes and other missiles out of Cuba. If that's not defensive, what it?
In fact, "barricade" is less defensive than "blockade" because police put up barricades all the time when they are not being defensive at all, they have all the power. Whereas blockades are always when a nation is getting out of hand and other countries act to hem them in, keep them from carrying out offensive actions.
Huzzah, full marks. Pleased with my brain for giving me 'accolade' and 'pomade'. I love finding out I know words but haven't the first clue why I know them.
Could you pleassee add tardigrade, it islike the greatest thing ever haha They are like a microscopic cross between a caterpillar and a naked molerat wearing a gasmask (with a touch of gummibear)They are aweome!
It was one of the first things I thought of seeing the quiz title. Thought it might be on nr2 but wasnt there either. You could make the description something like: well several ways to describes it size, survival skills, gasmask look, the meaning of the name. I guess "micro-animal who looks like it is wearing a gasmask" or more difficult, whose name means slow walker
