Answer: This is past simple tense.
Step-by-step explanation:
- Past simple tense is formed by adding -ed (in some cases, -d or -ied) to the base form of the verb. The past simple tense of the verb "to splurge" is going to be "splurged."
- Past progressive form, on the other hand, consists of verb to be and -ING verb form - "was splurging."
- Past perfect form would be "had splurged", while past perfect progressive would be "had been splurging."
