The best option here is 'fewer realize that', as it presents a lesser-known aspect of Henry Ford's legacy: his labor practices and their positive impact on the workforce. The other choices, 'hence', 'alongside', and 'due to,' are not suitable for connecting the sentence: 'Hence' suggests a cause-effect relationship, 'Alongside' combines two messages without emphasizing the lesser-known aspect, and 'Due to' indicates a reason-justification link.

'Likewise' is the most fitting option since it conveys that, in addition to Rebecca's technical expertise, her interpersonal abilities are also beneficial in the workplace. The other alternatives, 'Instead,' 'Although,' and 'Subsequently,' do not accurately convey this notion of another positive attribute: 'Instead' implies substitution, 'Although' creates an oppositional relationship, and 'Subsequently' suggests a sequence of events.

'As a result' is the optimal choice for this context because it establishes a cause-effect relationship between the strengths of solar energy and the continued research and development endeavors to enhance its potential. The other options — 'On the other hand,' 'In turn,' and 'Once again' — do not effectively denote this relationship: 'On the other hand' introduces contrast, 'In turn' conveys a sequential or reciprocal effect, and 'Once again' repeats a previous statement or occurrence.

'Additionally' is the most appropriate choice, as it presents extra information about the benefits offered by the community garden: its provision of fresh produce for participants. The other options — 'In contrast', 'Regardless', and 'Despite' — do not effectively indicate the addition of supportive information: 'In contrast' suggests a differing point, 'Regardless' implies that the sentence disregards a factor or condition, and 'Despite' introduces information that contradicts expectations.

The best-fit option here is 'While,' which creates a balanced contrast between the mall's positive features (shops, dining, and leisure) and its negative impacts (traffic and displacement of local businesses). The remaining choices — 'Because,' 'Incidentally', and 'Furthermore' — do not establish a clear contrast between the advantages and disadvantages: 'Because' presents a cause-effect relationship, 'Incidentally' indicates that the information is a coincidental observation, and 'Furthermore' expands on existing ideas without contrasting them.
