A. Homo erectus had estimated control of fire 700,000 years ago, although other hominid groups might have even mastered fire earlier --> Estimated control means they were estimating to control but didn't actually control. Modifier placement issue. OUT.
B. Homo erectus is estimated to have controlled fire 700,000 years ago, and other hominid groups even had mastered fire earlier --> Using 'and' changes the meaning of the sentence.
C. it is estimated that Homo erectus had control of fire 700,000 years ago, although other hominid groups might have mastered fire even earlier
D. it is estimated for Homo erectus to have controlled fire 700,000 years ago, although other hominid groups might even have mastered fire earlier --> We were estimating for Homo Erectus?? lol. Are they our relatives or what? OUT.
E. 700,000 years ago, Homo erectus is estimated as having controlled fire, with other hominid groups even having mastery fire earlier --> Misplaced modifier issue and having controlled fire is wrong usage.
B. Homo erectus is estimated to have controlled fire 700,000 years ago, and other hominid groups even had mastered fire earlier --> Using 'and' changes the meaning of the sentence.

From a cache of burnt bones, including bone tools, found in South Africa, Homo erectus had estimated control of fire 700,000 years ago, although other hominid groups might have even mastered fire earlier.
The 1st thing to notice here is that the prepositional phrase From a cache of burnt bones, including bone tools, found in South Africa, incorrectly modifies the Verb had estimated whose subject is Homo Erectus. Prepositional phrases can modify Verbs or Nouns. It is nonsensical to say Home erectus had estimated control of fire from a cache of burnt bones found in South Africa.
A. Homo erectus had estimated control of fire 700,000 years ago, although other hominid groups might have even mastered fire earlier
Incorrect as explained above
B. Homo erectus is estimated to have controlled fire 700,000 years ago, and other hominid groups even had mastered fire earlier
Same as A
C. it is estimated that Homo erectus had control of fire 700,000 years ago, although other hominid groups might have mastered fire even earlier
Here the modifier issue is resolved. This choice correctly conveys the meaning that It is estimated from a cache of burnt bones found in South Africa that homeo erectus had control of fire.
D. it is estimated for Homo erectus to have controlled fire 700,000 years ago, although other hominid groups might even have mastered fire earlier
This choice seems to resolve the Original modifier error but introduces another error by using For homo erectus. This again nonsensically conveys It is estimated from a cache of burnt bones found in South Africa for Homeo erectus that homeo erectus had control of fire.
E. 700,000 years ago, Homo erectus is estimated as having controlled fire, with other hominid groups even having mastery fire earlier
Again modifier error as choices A and B
Hope it helps !
