(1) Fluorescent proteins are found in bioluminescent sea creatures, such as jellyfish. (2) In 1969, the green fluorescent protein was discovered and, since then, prolific research has resulted in the discovery and development of many new fluorescent proteins. (3) Fluorescent proteins can be expressed in cells, making them easily visible under a microscope. (4) In fact, the use of fluorescent proteins revolutionized bio-imaging because the inherently natural nature meant that they could be incorporated into living cells with no deadly toxic effects. (5) Numerous other scientific and medical applications also exploit the unique properties of fluorescent proteins, which is why they were the subject of the 2008 Nobel Prize for Chemistry. (6) However, the science behind fluorescent proteins is still not fully understood, and there are many more avenues for exploration.What is implied by the fourth sentence of the passage?
Answer(s): D
The sentence states that bio-imaging was revolutionized because fluorescent proteins could be put into living cells without deadly toxic effects. The word "revolutionized" is very powerful and the sentence implies that "deadly toxic effects" prevented bio-imaging in live cells before fluorescent proteins were discovered.

Answer(s): C
The term fluorescent protein(s) is used 7 times in the passage and abbreviating it would help to make the passage more readable and more easily understood.

The conclusion is given in the final sentence of the passage and states that the subject is still open.
Breast milk is proven to be the best form of nutrition for infants and is recommended for at least 1 year after birth. Unfortunately, a recent survey of breastfeeding mothers revealed that only 20% continue breastfeeding or to provide breast milk through pumping after 4 months, after which they switch to formulA. When asked about reasons for stopping breastfeeding, the top three reasons were: going back to work, lack of support, and difficulties pumping. A socioeconomic study of the mothers revealed that women who choose to breastfeed for longest tend to have a higher level of education and come from more affluent backgrounds. Conversely, those mothers who breastfeed for the least amount of time tend to belong to minority groups and are from poorer backgrounds. It has been proposed that cultural differences also have a significant impact on the duration of breastfeeding.Which statement would be supported by the knowledge that out of the women who took part in the socioeconomic survey, 2% were from a minority background?
More responses from minority mothers are needed to make solid comparisons based on ethnicity.

The passage states that minority groups from poor backgrounds tend to breastfeed for the least amount of time and also highlights the importance of cultural differences. These factors imply that minority groups would need to be primarily considered when developing a campaign.
