Oh, not very well. I’ve got all the information, but I can’t seem to organise it into a presentation.Q10

Yes, that’s OK, it’s just that…ohh….(sound of desperation)

Really? Great! OK, well I’ve chosen solar power for my subject, and I’m going to talk specifically about domestic water heating.Q22 You know, like the ones popular in America. I’ve got some facts here…

Oh, right. Here we go then. There are many reasons why we should be looking elsewhere for energy sources. As most people are aware, fossil fuels and other such non-renewable sources are by definition finiteQ23, so something needs to be in operation soon. Currently, there are a number of alternative energy sources available which can, with a little preparation, be used to provide for a significant part of our domestic energy requirements. In this presentation I am focusing solar power and its application as a domestic water heater. As a renewable energy source, solar power is in many ways ideal. The amount of the sun’s energy which reaches the Earth every minute exceeds the energy that the global population consumes in a year. Although scientists argue that it is not finite, sunlight is certainly a long-lasting resource which is not depleted through use, and solar power converters use this energy without needing any complex moving parts.Q24 Once collected and stored, solar energy can be used for many purposes, but it is becoming increasingly popular as a domestic heating source. Generally, a building that is heated by solar power will have its water heated by solar power well, and this has even worked in areas that are not exposed to long hours of as direct sunlight such as the United Kingdom, although not so well as in warmer climates (long pause)

Well, that’s all I’ve got so far.

Oh, OK. Well, there are a number of factors that influence how efficient solar power can be. The first, obviously, is the amount of sunlight, and this is dependent on season, time of day, and climate. Although the UK has something of a bad reputation for sunshine, it is actually quite productive during some parts of the year. Given a sufficient size of solar panel and water storage tank, solar power can provide all of our water-heating requirements in June and July, and even provide the majority until October.

C

Ans- A – this answer seems to cause a lot of confusion, so to clarify, the speaker says ‘can provide the majority until October’ – that means you are looking for a graph where October DOES NOT supply the majority (e.g. 50% or more), and that leaves only Graph A.
