The discovery of penicillin by Alexander Fleming revolutionized the field of medicine . By disrupting the cell walls of harmful bacteria , penicillin prevents infections from spreading . This antibiotic., which became widely available during World War II. __ helped in the treatment of bacterial infections and saved countless lives. A) was instrumental . Penicillin B) was instrumental penicillin C) was instrumental and penicillin D) was instrumental , penicillin Mohamed Fawzy -SAT &ACT English By utilizing cutting -edge technology and materials in construction, __ The new skyscraper in downtown Chicago for example . was built using these advanced methods , making it both earthquake -resistant and energy -efficient. A)architects and engineers are able to design buildings that are more durable and sustainable. B)architects and engineers making buildings that are more durable and sustainable. C)architects and engineers who design buildings that are more durable and sustainable. D) while architects and engineers are able to make buildings more durable and sustainable. Mohamed Fawzy -SAT & ACT English From an evolutionary point of view, it's not surprising that primates and humans have von Economo cells, since we are in the same lineage . But primates and humans haven't shared an ancestor with whales or elephants since about the beginning of the mammalian lineage, some sixty million years ago . It seems that cetaceans and elephants evolved their spindle cells independently. What factors would produce such emotionally specialized brain cells? The main point of this paragraph is that: A) at the beginning of the mammalian lineage, primates and humans shared ancestors with whales and elephants. B)primates and humans are in the same lineage. C) some animals seem to have been able to develop von Economo cells independently from primates and humans. D) von Economo cells can be described as "emotionally specialized brain cells."

## Step 1The first question is a sentence completion question. The sentence is about the discovery of penicillin by Alexander Fleming and its impact on medicine. The correct answer is A) "was instrumental Penicillin". This is because the sentence is about the impact of penicillin, and the verb "was instrumental" is used to describe the impact. The word "Penicillin" is used to clarify what the sentence is about.## Step 2The second question is a sentence completion question. The sentence is about the construction of a skyscraper in Chicago. The correct answer is A) "architects and engineers are able to design buildings that are more durable and sustainable". This is because the sentence is about the ability of architects and engineers to design buildings that are more durable and sustainable. The phrase "architects and engineers are able to design buildings that are more durable and sustainable" is used to explain this ability.## Step 3The third question is a multiple-choice question. The paragraph is about the evolutionary history of von Economo cells in primates and humans. The correct answer is C) "some animals seem to have been able to develop von Economo cells independently from primates and humans". This is because the paragraph is about the independent development of von Economo cells in some animals, not about the shared ancestry of primates and humans with whales and elephants.## Step 4The fourth question is a sentence completion question. The sentence is about Carmen Leigh's experiences in the marine biology field. The correct answer is C) "has been". This is because the sentence is about the past recognition of Leigh's research, and the verb "has been" is used to describe this past recognition.
