Circumstantial evidence suggests that if the basic building of life are seen scattered in space, why not life itself? In the sixties, there started inter-disciplinary discussions about life. The astronomers can tell what the likely sites for life are and how many of them are there in our Milky Way Galaxy of stars. Biologists have to decide what is it that the life-mechanism and where among the various astronomical sites it is likely to occur. Then, the evolutionists have to say how a simple living system can develop over what time into a complex intelligent species. Experts in artificial intelligence, communications and information transfer are needed to resolve the problem of contacting such species if they . And the social scientists need to assess the lifetime of an advanced civilization.

Result:

A.I. Explanation:

Correct answer: blocks
Explanation: The term 'blocks' fits grammatically as a plural noun that refers to fundamental units or components, aligning with the context of 'building blocks of life.' It indicates the basic elements that constitute life, making it contextually appropriate.
Meaning: 'Blocks' refers to the essential components or units that make up a larger structure, in this case, the fundamental elements of life.
Wrong options:
cells: 'Cells' refers specifically to biological units and does not convey the broader concept of foundational components in this context.
spans: 'Spans' suggests a range or extent, which does not align with the idea of basic components of life.
designs: 'Designs' implies a plan or arrangement, which is not suitable for describing the fundamental units of life.
Correct answer: extra-terrestrial
Explanation: The term 'extra-terrestrial' is the correct choice as it specifically refers to life forms that originate outside of Earth, fitting the context of discussions about life beyond our planet.
Meaning: 'Extra-terrestrial' means originating, existing, or occurring outside the Earth or its atmosphere, particularly in reference to life forms.
Wrong options:
alien: 'Alien' can refer to foreign entities but lacks the specific scientific context of life beyond Earth that 'extra-terrestrial' provides.
native: 'Native' implies origin from a particular place, which contradicts the idea of life from outside Earth.
celestial: 'Celestial' refers to heavenly bodies or space but does not specifically denote life forms, making it less precise in this context.
Correct answer: triggers
Explanation: The word 'triggers' is appropriate as it indicates an action that initiates or causes a response, fitting the context of what activates the life-mechanism.
Meaning: 'Triggers' means to cause something to happen or to initiate a process, particularly in a biological context.
Wrong options:
imperials: 'Imperials' refers to something related to an empire or authority, which does not fit the context of biological mechanisms.
evokes: 'Evokes' suggests bringing something to mind or calling forth, which is not as precise as 'triggers' in describing an initiating action.
twigs: 'Twigs' refers to small branches and is unrelated to the concept of initiating biological processes.
Correct answer: span
Explanation: The word 'span' fits grammatically as a noun indicating a period or duration of time, which aligns with the context of how long a simple living system can develop into a complex species.
Meaning: 'Span' refers to the extent or duration of time over which something occurs, particularly in developmental contexts.
Wrong options:
test: 'Test' implies an examination or assessment, which does not fit the context of time duration for development.
gap: 'Gap' suggests a break or interval, which does not convey the continuous process of development implied in the sentence.
sequence: 'Sequence' refers to a specific order of events, which does not accurately represent the idea of time duration in this context.
Correct answer: exist
Explanation: The word 'exist' is the correct choice as it denotes the state of being present or alive, which is essential in the context of contacting advanced species.
Meaning: 'Exist' means to have actual being or presence, particularly in reference to life forms.
Wrong options:
hold: 'Hold' implies possession or retention, which does not fit the context of life forms being present.
desire: 'Desire' refers to wanting or wishing for something, which is not relevant to the existence of species.
die: 'Die' indicates the cessation of life, which is contrary to the context of discussing the presence of advanced civilizations.
