These hands are painted to look like a bacteria. The ad is about washing your hands to eliminate bacteria, which is clever because if this person washes their hands the paint will come off, thus getting rid of the bacteria. This is effective because there is a clear message. You can draw many parallels between what the image is telling you and what the words are saying to you.

This ad has two parts, the first part with the apple making it look like an Apple products says "One dies, million cry" and the next part with the continent of Africa says "Millions die, no one cries." The ad is not to attack Apple products, it is to raise awareness on issues happening around the world that no one pays attention to because they are absorbed in their phones, computers, tablets, etc. The message is clear and concise, you understand what they are talking about, and it gets to the point simply and effectively.

This is an ad for parenting which says that losing patience means a lot more than just that. You could injure your child and thus lose your child due to abuse. The image shows that the child is fragile, that is why he is visibly broken, and he is crying, which shows that he is hurt and upset by you losing your patience. This ad is effective, it shows how much impact it could have if you lose patience in a destructive way even once. And the text, while simple portrays a bigger message and helps being the ad together so you can tell what it means.
