Identify the past tense of the verb ‘spring’ from the options given below.

After introducing "tense forms" to grade 5 students, a teacher set up a pair activity: Student A takes a piece of text in simple present tense from a book and conveys it to Student B in past tense. Student B tries to guess what the present tense would have been. Student A modifies his conversion from present to past tense if needed, repeatedly, till Student B guesses correctly. The above activity MOST closely represents...

Krashen's Input hypothesis

B

Swain's Output hypothesis

C

Bruner's theory of development

D

Krashen's Acquisition-Learning hypothesis

A

$$\frac{{{\text{W}}{{\text{D}}^3}{\text{n}}}}{{{\text{C}}{{\text{d}}^4}}}$$

B

$$\frac{{2{\text{W}}{{\text{D}}^3}{\text{n}}}}{{{\text{C}}{{\text{d}}^4}}}$$

C

$$\frac{{4{\text{W}}{{\text{D}}^3}{\text{n}}}}{{{\text{C}}{{\text{d}}^4}}}$$

D

$$\frac{{8{\text{W}}{{\text{D}}^3}{\text{n}}}}{{{\text{C}}{{\text{d}}^4}}}$$

B

$$\tau $$

C

$$2\tau $$

D

$$4\tau $$
