1. _is one disease that is growing after having been eradicated.
Keywords: one disease, grow, after eradicated.
We need to find out the most appropriate disease, one which is ‘growing’. In paragraph D, the author mentioned some diseases that need a better cure. One of them is polio which is reemerging. “Emerge” means to to appear, and “re” is a prefix used with the meaning “again”. We can understand that polio is a disease that can appear again (after being treated or eradicated). Therefore, the answer is polio.
Answer: polio.
1. A physical barrier such as a _ can prevent people from reaching a hospital.
Keywords: physical barrier, prevent, reach a hospital
The word needed is after an article and stands in front of a verb. Therefore, it has to be a noun. “Hospital” is mentioned once in the passage in paragraph G,in which the author took an example of people’s attempt to assess the levels of healthcare. The writer states: “it may be very difficult for people to get medical attention because there is a mountain between their village and the nearest hospital”. What prevents people from getting to their nearest hospital is a mountain (a physical barrier). Therefore, the noun we’re looking for is “mountain”.
Answer: mountain.

27 + 28. It was noted that the music stimulated the brain’s neurons to release a substance called _ in two of the parts of the brain which are associated with feeling .
Keywords: music, stimulate, brain’s neurons, release, substance, two of the parts of the brain, associated, feeling
In the last sentences of the second paragraph, the author wrote “The first thing they discovered is that music triggers the production of dopamine – a chemical with a key role in setting people’s moods – by the neurons (nerve cells) in both the dorsal and ventral regions of the brain. As these two regions have long been linked with the experience of pleasure, this finding isn’t particularly surprising.” “Trigger” means “to cause something to start” and can be considered as “stimulate”. It is said that music stimulates the production of a chemical called dopamine. “A chemical” is the same as “a substance” and “production” is the same as “release”. Therefore, “dopamine” is what we’re looking for in question 27. After that, the author mentioned two regions of the brain and claimed they “have long been linked with the experience of pleasure.” “Linked” refers to “associated” (to be connected), and “feeling” means “experience”. Hence, the answer for question 28 is “pleasure”.
stimulate = trigger
substance = chemical
associated = linked
