Answer:
Arranged from the most reliable to least reliable
1: An article in a business journal about the rise of pet-friendly businesses
2: An article by the Centers for Disease Control (CDC) about hygiene in pet-friendly businesses
3: A website owned by a business that sells pet products
4: A personal blog detailing an experience at a pet-friendly café
Explanation:
1: An article in a business journal has thoroughly researched content written by experts in that specific business.
2: An article by Centers for Disease Control (CDC) is also reliable and will provide useful information about possible diseases and their precautions/treatments.
3: A website owned by a business that sells pet products, although not much reliable, will provide insights into different products. It is less reliable as business websites usually exaggeratedly portray many things.
4: A personal blog could be least helpful as they are mostly written from SEO (Search Engine Optimization) point of view to increase web-traffic, and may contain limited help in a specific case.
It's PQRS, the one in the middle
I believe it's persuade. You want to persuade schools to offer better food. B is wrong because you are not entertaining anyone. Inform is wrong because you would just be stating facts. A is wrong because you are not telling someone to do something. Hope this helps! ;)
