Correct Answer: A

Rationale: The correct answer is 'Chinese.' In the context of ancient civilizations, 'Chinese' is appropriately used to refer to a very ancient culture like the Shang dynasty (c. 1600-1046 BC) or the Zhou dynasty (1046-256 BC). The other choices ('The Greeks,' 'Romans,' and 'Egyptians') are also ancient civilizations, but they are not the best fit in the given sentence as they do not match the description of 'very ancient people.' The Greeks, Romans, and Egyptians are ancient too, but 'very ancient people' specifically points towards Chinese civilization during its early periods. Therefore, 'Chinese' is the most suitable option.

Correct Answer: B

Rationale: The correct answer is B. 'Expand' means to increase in size or amount. Choice A, 'To decrease in size,' is the opposite of what 'expand' means. Choice C, 'To spread out,' is related to expanding but does not precisely define the term. Choice D, 'To eliminate,' is not synonymous with the term 'expand.'

Correct Answer: B

Rationale: Being overweight increases the risk of developing conditions like diabetes. Excessive weight can lead to insulin resistance and metabolic dysfunction, which are key factors in the development of type 2 diabetes. While obesity is a result of being overweight, it is not a condition that being overweight predisposes a person to. Cancer and heart disease can also be influenced by weight but are not the primary conditions typically associated with being overweight.

Correct Answer: A

Rationale: The correct answer is A: 'patient.' The correct spelling should be 'patient.' 'Physician,' 'sodium,' and 'recommended' are all spelled correctly. 'Physician' refers to a medical doctor, 'sodium' is a chemical element, and 'recommended' is the past tense of the verb 'recommend.' Therefore, the misspelled word in the sentence is 'patient.'

Correct Answer: B

Rationale: The correct answer is B: 'Exhausted.' Lethargic describes a state of feeling sluggish, tired, and lacking energy, which aligns with being exhausted. Choice A, 'Energetic,' is the opposite of lethargic and does not fit the description. Choice C, 'Confused,' refers to a state of disorientation rather than physical tiredness. Choice D, 'Restless,' implies a state of agitation or inability to relax, which contrasts with the typical presentation of someone who is lethargic.
