Question

4. For the last year.an international team of scientists the plant fossils and sediment found in the ice core found in Greenland to determine its composition and age. A)analysed B)had analysed C) have been analysing D) used to analyse E)were analysing

Answer 1

) analysedThe correct answer is A) analysed. The sentence is in the past tense, and the verb 'analysed' is the simple past tense form of 'analyse'. The sentence is describing an action that was completed in the past, so the simple past tense is the appropriate tense to use. The other options, B) had analysed, C) have been analysing, D) used to analyse, and E) were analysing, do not fit the tense and context of the sentence.
