Answer 1

"Some time ago, an interesting discovery was made by archaeologists on the Hegou Island of Kec." This will be the complete sentence.

• Here, we have to fill in the given blanks with a word from among the given options.
• 'Had to be made' will not be correct. It shows a necessity or a compulsion about making the discovery. No such thing can be inferred from the sentence.
• 'Was made' will be correct. It is clear from the sentence that it is in the past tense, thus a word in the past tense needs to be used. 'Was made' is in the past tense.
• 'Has been made' is incorrect. It indicates a sentence that is in the present continuous tense. But, the givens sentence is in the past tense.
• 'Is made' will not be correct. It is in the present tense but the sentence is in the past tense.
• Hence, the correct answer will be option B, 'was made'.
• The complete sentence will be, "Some time ago, an interesting discovery was made by archaeologists on the Hegou Island of Kec."

Answer 2

Answer: option b

Explanation:

• On Kec's Hegou Island, archaeologists recently found an intriguing discovery. This will be the last sentence.

• Here, we must select a word from the list of options to complete the sentences.
• Not accurate will be had to be made. It shows a need for or compulsion to reach the conclusion.
• The statement does not imply anything of the type.
• Was made is the correct phrase. Since the sentence's past tense is clear from the sentence itself, a past tense word must be used.
• The past tense of the verb is made.
• It's untrue to say "has been made." The sentence implies the present continuous tense.. 
• The offered sentence, however, is in the past tense.
• It won't be correct to say "is made." Although the sentence is in the past tense, it is in the present tense.
• As a result, option B, "was made," will be the right response.
• "Some time ago, archaeologists on the Hegou Island of Kec unearthed an amazing discovery," will be the whole text.
