1) Both sentences are grammatically correct and convey the same message, but there is a slight difference in meaning.

The first sentence, "Their objective is to show people how to defend," implies that the main objective of ads is to teach people how to defend.

The second sentence, "They aim to show people how to defend," suggests that showing people how to defend is one of the objectives of ads, but not necessarily the main one.

2) The sentence "The use of children in ads is an exploitation of the children's image" is grammatically correct and conveys the idea that using children in advertisements is an exploitation of their image. It implies that their image is being exploited for commercial gain.

The sentence "It's a way to earn audience as well as to sell a major number of products" is also grammatically correct. It suggests that using children in ads is a strategy to attract a larger audience and to sell a larger quantity of products.

3) The sentence "It is also a way to show children a lifestyle which doesn't exist" is grammatically accurate. It means that using children in ads can portray a lifestyle that doesn't actually exist, creating a false impression on children.

The sentence "If children see other children doing amazing things on TV, they think they can also do these things" is grammatically correct and highlights the impact of ads on children's perception. It suggests that when children see other children performing impressive acts on television, they might be inclined to believe that they can achieve the same extraordinary feats.

4) The sentence "The biggest risk is that our children could grow up with a wrong idea of life" is grammatically correct. It means that one of the major risks associated with ads involving children is that children may develop incorrect or distorted perspectives on life.

5) The sentence "Ad-busters" means destruction of the ad" is grammatically correct, but the meaning is slightly inaccurate. "Ad-busters" refers to a magazine or movement that critiques and challenges advertisements, aiming to expose their falseness and flaws. It does not necessarily imply the destruction of ads, but rather the deconstruction and critique of their messages.

6) The sentence "The use of children in ads can transform them into the victims of advertising" is grammatically correct. It suggests that involving children in advertisements can potentially turn them into targets or vulnerable individuals susceptible to the influence and manipulation of advertising.
