Hehe, always feel free to ask ^^
Wow, trials for trials... that must've sucked.
Hmmm i never really paid much attention in yr 10 history to be honest and i don't think i've ever learnt about the impacts of technology. However, if i had to answer that question i'd mention the oven, washing machine and gas cooktops etc etc and how they made life easier, raising standards of living. Vacuum cleaners would count as a housing appliances so you probably answered that question fine
Sorry for the delayed reply, i was doing some maths XD
I doubt they'd ask that question again anyway seeing as they asked it in your trial-trials ^^
