2005 Paper Summary

Nearly half the homes in the developing world were without light. This Calgary engineer wanted to change that. Irvine Halliday worked endlessly for months to invent an efficient energy source for powering a light. Using your own words as far as possible, write a summary to show the difficulties Irvine-Halliday faced and the ways he overcame these difficulties. USE ONLY MATERIAL FROM LINES 35 to LINES 80. Your summary, which must be in continuous writing (not in note form), must not be longer than 160 words, including the 4 words given below. Begin your summary as follows: Irvine-Halliday concentrated on ……

Pt Lifted from Text 1 and his attempts to bunch a few together to create a light someone could read by failed miserably given their limited strength. (lines 38-39) 2 He moved on to coming up with an energy source to power a light. (line 40) 3 But to do so would cost money. (line 40-41) 4 ….the couple decided to finance the equipment …. with their savings and three credit cards, …… (lines 43 – 45) 5 For hours on evenings and weekends over the next several months,IrvineHalliday experimented. (Line 47 – 48)

And he carefully considered wind and solar power, but ruled both out as unfeasible and overly expensive (lines 49-50) One day nearly two years after his Nepal trip, IrvineHalliday sat at his

Finally after researching from the internet (9) persistently for two years (8), he found the new diodes from a Japanese company (10) and quickly made an order (11). Hoping it would work well this time (12), they quickly tested it out upon arrival (13). They used a piece of paper to test the brightness of the light (14). It emitted bright light/lit up successfully this time (15). He was further challenged with providing a cheaper source of energy (17) for the light because it would take more than one diode to light up a bigger area (16). Therefore, he had to think of an alternative power source (18) which was more functional (19). He began to work on building a pedal generator (20) which could serve other purposes too(21). He finally created a practical lamp after many experiments (22). (171 words)
