my point was simple questions that require simple, one word, case insensitive answers. regardless of the type of site one is visiting. the color of blood (three letter word), what is a three letter word for frozen water, what do chickens lay that has a yolk...
and if, in turkish, the word ice has seven letters, then the question, which would be in turkish when on a turkish site, would reflect that.
the point isnt to check for capitals or proper use of apostrophes. the point is that unless a bot is built to recognize specific questions and have a matching answer, it shouldnt be able to enter a correct response. multiple choice questions might be easier but a bot can be built to guess an answer.
an issue that i believe would make textual captcha useless is if the questions are presented too simply, such as the ones above, you could probably build a bot that passes the question to a search engine and tries to determine which word is the answer based on the first page of the results. so maybe it would work better in the form of:
blood is: [input box] hint: color, 3 letters
again, this is a harder system to develop than the current because it requires a lot of creativity while maintaining simplicity and you dont have the option of random generation. but if done correctly, its easier for humans yet just as difficult (if not more) to decipher programmatically.
chances are that if youre going to a site, you know enough of that sites language to at least be able to navigate through it. simple answers to simple questions shouldnt be difficult if the site is not in your first language, but you know enough of the sites language to navigate through it. so neumáticos would be the correct answer on the italian site.
the site dictates how the answer should be spelt. if you are joining a site that has all its content in commonwealth english (you know what i mean), then obviously tyres would be the correct answer.
although it would require more work to have a database of simple questions and their answers, it would beat the captcha system.
it can be answered by people with visual disabilities as its just text and an input box, something screen readers have no trouble with.
and if due to learning disabilities one does not know that the color of cloudless midday sky is blue or the four round rubber things a car uses to move are tires, then chances are this person has somebody helping them with their daily activities.
