According to the text 'Back to nature', which type of energy is considered the most viable for Algeria due to its cleanness and consistent availability of sun rays?

• Wind energy
• Solar energy
• Hydroelectric energy
• Geothermal energy

The text explicitly states that 'The most viable energy source for Algeria is solar energy because of its cleanness and the availability of sun rays in the Sahara almost all the year round.'

In the 'Back to nature' lesson, which energy source is described as 'clean but intermittent and noisy'?

• Solar energy
• Biomass energy
• Wind energy
• Ocean energy

The table in the lesson lists 'Wind' energy with the advantages/drawbacks 'clean but intermittent and noisy'.

The paragraph 'Back to nature' states that the introduction of alternative fuels can consistently reduce pollution and improve the environmental situation worldwide. What is identified as the major cause of environmental pollution?

• The use of renewable energy sources
• The emission of CO2 from solar panels
• The use of fossil fuels
• The production of biomass energy

The text says, 'In such a situation, the use of fossil fuels is the major cause of the environmental pollution.'

According to the 'Back to nature' lesson, which of these energy sources is described as 'clean but too demanding in terms of water'?

• Solar energy
• Wind energy
• Geothermal energy
• Hydroelectric energy

The table in the lesson lists 'Geothermal' energy with the advantages/drawbacks 'clean but too demanding in terms of water'.

In the context of waste management discussed in 'Back to nature', what does the term 'reduce' primarily involve?

• Throwing away items that cannot be used again
• Buying less and critically evaluating what we use
• Recycling all plastic bags
• Composting all food waste

The text explains 'Reduce' as 'While it seems simple to just buy less, we humans can be very set in our ways, relying heavily on products to which we are loyal. To truly implement this step, it's important to cast a critical eye on what we use, and ask: What could we do better? What don't we need?'

The 'Getting Through' lesson introduces polite requests. Which of the following is an example of a formal polite request?

• Can you show me how to do it, please?
• Could you speak more quickly?
• Please drive less quickly.
• I don't know how to use my new smart phone.

The lesson defines formal polite requests with the structure 'Could + subject + infinitive form of the verb + complement?' and provides 'Could you speak more quickly?' as an example.

According to the 'Getting Through' lesson, when do we typically use formal polite requests?

• When talking to close friends
• When asking for instructions from people we do not know very well
• When making demands
• When expressing strong opinions

The lesson states, 'Formal polite requests made to people we do not know very well.'

The 'Back to nature' lesson discusses the problem of environmental protection. What is presented as a major cause of environmental pollution that threatens mankind and numerous species?

• The widespread use of solar energy
• The reliance on fossil fuels
• The increase in biomass production
• The development of hydroelectric power

The text states, 'In such a situation, the use of fossil fuels is the major cause of the environmental pollution.'

In the 'Back to nature' lesson, the paragraph on waste management suggests that children should be taught about 'reduce, reuse, recycle'. What is one of the key questions to ask when trying to 'reduce' waste?

• How can we reuse this item?
• Can this item be recycled?
• What don't we need?
• Where can we dispose of this waste?

The text explicitly asks, 'What could we do better? What don't we need? What is made of a harmful substance, and can be replaced with something less harmful - or eliminated altogether?'

The 'Back to nature' lesson highlights that modern industries and transport cannot function normally without the use of fossil fuels. However, it also points out a significant downside. What is this downside?

• They are too expensive to produce.
• They lead to the emission of CO2 and other polluting gases.
• They are not a viable energy source for most industries.
• They require excessive amounts of water.

The text states, 'At the same time, fossil fuels are the major source of the pollution of the environment because the use of fossil fuels leads to the emission of CO2 and other gases and dangerous elements that pollute air and environment at large.'
