Answer:

Answer 2

Kalpana has joined the NASA Astronaut training camp.

Explanation:

• The present perfect tense is a tense form which is used to relate two time spaces.  One is in the recent past and the other the present.  

• The has or have auxiliary verb is used along with the past perfect form of the verb.

• In the given sentence:  Kalpana joined the NASA Astronaut training camp. The subject is 'Kalpana'. It is in the singular aspect.  

• It is thus followed by the auxiliary verb 'has'.  The past participle form of the verb 'join' is joined.

• Hence the sentence in the present perfect tense is: Kalpana has joined the NASA Astronaut training camp.
